Reasoning is crucial for understanding situations or solving problems and involves using logic and evidence. Two types of reasoning are discussed: inductive and deductive. Inductive reasoning involves making generalizations from specific observations, which leads to probable but not certain conclusions. An example given is observing that the sun rises in the east on multiple days and inferring that it always does. Deductive reasoning, on the other hand, starts with a general statement and applies it to a specific case to reach a certain conclusion, which is guaranteed to be true if the premises are correct.
🌱 Inductive and Deductive Reasoning in Daily Life
This paragraph delves deeper into the practical applications of inductive and deductive reasoning. Inductive reasoning is illustrated through everyday examples such as inferring the quality of food at a restaurant based on past experiences. Deductive reasoning is explained as a top-down approach, starting with a general statement and reaching specific conclusions. Examples are provided to clarify the difference between the two types of reasoning, such as predicting the fruit in a bowl based on a sample or concluding that Socrates is mortal because all humans are mortal.
📊 Comparing Inductive and Deductive Reasoning
The paragraph presents a comparison chart to differentiate between inductive and deductive reasoning. It highlights the direction of reasoning, with inductive reasoning moving from specific observations to general conclusions and deductive reasoning moving from general principles to specific conclusions. The certainty of conclusions is also contrasted, with inductive reasoning offering probabilities and deductive reasoning providing certainty if the premises are true. Examples are given to illustrate how each type of reasoning is applied in different scenarios.

hello every everyone welcome back to the
channel now we are going to dig deep
into mastering the art of learning and
problem solving today we are going to
talk about something that's a game
changer whether you are tackling math
science or everyday
challenges problem solving and reasoning
skills so in this video we will break
down some powerful strategies that can
help you to think more clearly solve
problems faster and approach every
challenges with confidence whether your
students trying to e the exam or someone
who just looking to sharpen their mind
stick around because these tips are for
you uh from looking for the patterns to
working backwards and using logic I'll
be walking
through uh by step byst step guide to
boost your problem solving skills so
grab your pen take some notes and let
let get dive right into it so let us
first Define reasoning so reasoning is
the process of drawing conclusions or
making
inferences based on information facts or
premises that we have wherein reasoning
is the process of our thinking through a
problem or situation to reach a
conclusions or making
decisions it involves using logic
evidence critical thinking to connect
ideas and draw conclusions there are
different types of reasoning but there
are all shares the goal of helping us to
understand things better or solve
problems by reasoning we can analyze
situations make predictions and decides
what actions to take so in simple terms
reasoning is like solving a passle with
your mind you look at the pieces for
example the facts the observations or
ideas that you have and try to fit them
together in a way that makes sense it is
the process we use to figure things out
whether it's deciding what to have for
dinner or understanding a complex
scientific Concepts so now let us have
with two types of reasoning so we have
the inductive reasonings which is
inductive reasoning is the process of
getting a general conclusions by
observing a specific examples or sets so
here in inductive reasoning we are
conducting an approach which is bottom
up which is this is a type or of logical
thinking that involves making
generalizations based on specific
observations or
experiences it starts with noticing
patterns or specific examples and and
then infer a broader conclusions from
them unlike deductive reasonings which
guarantees the truth of the conclusion
if the premises are true inductive
reasoning leads to conclusion that are
probable but not certain okay so for
example the sun rose in the east on
Monday the sun rose in the east on
Tuesday the sun rose in the east on
Wednesday so therefore
the sun always rises in the East so by
this example so this is an inductive
reasoning
wherein we don't have the
certainty which is it will the sun will
always rises in the East based on our
observations because the data that we
have here right now is limited or we
cannot give conclusion by those
observation that we conclude by the sun
rose in the east on Monday and also on
Tuesday on and on Wednesday so the key
the key characteristic that you need to
uh look here
is there is a conclusion that is likely
to be true in this statement but there
is no guarantee that it will always be
true so there is always a chance that
future
observations could contradict the
generalizations so bottom up approach as
we said earlier this is an inductive
reasoning moves from specific cases to
broader uh
generalizations okay so use in everyday
life wherein we often use inductive
reasoning in Daily decisions like
expecting a restaurant to serve good
food because it has done so in the
past okay so for example um um if you if
you taste a few strawberry from a bowl
they are all sweet rather so you might
conclude that all the strawberries in
the bowl are sweet this conclusion is
based on inductive reasoning wherein
however there there is a chance that not
all the strawberries are sweet so your
generalizations is based on limited
observations so in summary inductive
reasoning help us from General beliefs
or predictions based on specific
experiences or evidence that we have but
it does not guarantee that those beliefs
or predictions will always be correct
therefore there is
uncertainty particularly with inductive
reasoning while when we talk about
deductive reasoning this is the topd
down approach that we have deductive
reasoning starts with a general
statement and examines the possibilities
to reach a specific or logical
conclusions so it moves from General to
specific unlike inductive that is
specific to General so here right now
deductive reasoning is also a type of
logical thinking where you start with a
general principle or premise and apply
it to a specific case to reach a certain
conclusion so it works from top down
meaning it moves from a broad idea
general statement to a specific or
logical outcome if the initial uh
premises are true and the reasoning
process is valid the conclusion drawn
through theed doct of reasoning will be
also true like for
example all humans are mortal Socrates
is a human therefore Socrates is is mar
so for like for example uh in this um
example is all humans are
Mor right and then we identify Socrates
is a human so now we can conclude that
therefore Socrates is Immortal so as you
can see in this statement our conclusion
it has certainty it could happen so
certainty if the premises are true and
the reasoning is correct the conclusion
is guaranteed to be true so topown
approach is we have with deductive
reasoning wherein it starts from general
idea and works its way down to specific
conclusions wherein you reasoning
process is valid if the conclusion NE
necessarily follows from the premises
okay so now let us have another example
all fruits have seeds an apple is a
fruit therefore an Apple has seeds so in
this this is a deductive reasoning since
the first premise or in the first
statement that we have this is a general
truth and the second uh statement is a
specific fact the conclusion follows
logically and must be true if the
premises are accurate so in summary
deductive reasoning is a powerful tool
for arriving at definite conclusion
based on general principles it ensures
that conclusions are logically sound but
its Effectiveness depends on the truth
of the starting premises so as we said
earlier deductive reasoning is General
to specific meaning we have General
principle general rule or Theory and
applying it to a specific case for
instance to reach a conclusions so you
start with a general rule apply it to
specific situations to reach your
specific conclusions okay so both
approaches are Essentials for different
types of reasoning and problem solvings
as we said inductive reasoning helps in
forming hypothesis or general theories
while deductive reasoning is used to
test or apply those theories in for uh
in um particular cases that we have now
let us have with comparison chart so in
comparison chart we have the
aspects
for the direction of the reasoning the
certainty of our conclusion and let we
have also another example and how we use
that certain reasoning that we have in
inductive and deductive reasoning so
moving from specific
observations example or instances to
from abroad General conclusions or
Theory so as we gathered our specific
instances instances and use them to form
a general rule or conclusions okay so
General to specific so starting with a
general principle rule or Theory and
applying it a specific case or instance
to reach a conclusion so that is
inductive while deductive reasoning you
start with a general rule and apply it
to a specific situation to reach a
specific conclusion that is why in
directions of reasoning particularly
with inductive that's specific to
General you have a specific conclusion
to General assumptions while um
deductive reasoning you have General
assumptions it goes to specific
conclusions in the aspects of certainty
of our conclusions in inductive
reasoning as a summary we have a
probability or we have
uncertainty and unlike with deductive we
have
certainty if the premises are true okay
so like for example in
inductive observing that all swans
you've seen are white and concluding all
swans are
white okay so that's inductive in
deductive reasoning all humans are
mortal
which is Socrates is a human so
therefore we can conclude Socrates is a
moral so how do we use an inductor
reasoning we have formulating hypothesis
and theories and in deductor reasoning
we use the aspect of testing our
hypothesis and theories okay like for
example this one let us identify if this
is inductive or deductive reasoning so
you can post the video and then you can
uh think of it what uh is it inductive
or
deductive okay so let us read the
statement during the past 10 years an
apple tree has produced plums every
other year last year the tree did not
produce Apple so this year the tree will
produce Apple okay so as our
observation over the past 10 years the
apple tree has produced plums every
other year so so it has a specific
pattern right so last year the tree did
not produce apples so it continues the
pattern so in this statement we
generalize our conclusion which is
therefore this year the tree will
produce Apple because
alternately the apple tree produce plums
every other year right so in this
reasoning you are using specific pass
observations so the tree will produce
apples every other year to predict a
general outcome for the current year so
the reasoning assumes that because this
pattern has held through in the past it
will continue this year as well but take
note while the conclusion may seem
likely based on the past pattern has
alternate uh produce plums every other
year it's important to
recognize that this this is an example
of inductive reasoning because it it
gives us or it does not give us
guarantee of the outcome there could be
other factors that can affect the tree
that it weren considered in the pattern
okay so that is why this is inductive
resoning now let us have another
example so all Home Improvements cost
more than the estimate so the contractor
estimated that my home improvement will
cost
35,000 pesos so thus my home improvement
will cost more than
35,000 pesos so as our general premise
or observations is all home improvement
cost more than the estimate second
observation that we can have the
contractor uh estimated that my home
improvement will cost 35,000 so
therefore we can have specific
conclusions my home improvement will
cost more than 35,000 so in this
reasoning you start with general rule
that all Home Improvements cost more
than the estimate so then you apply this
rule to your specific situations where
your home improvement is estimated to
cost 35,000 pesos So based on this
general rule you logically conclude that
your home improvement will cause more
more than
35,000 so since the reasoning follows
logically from the premises if the
premises are true the conclusion must be
true that is why this is an example of
deductive reasoning because you have a
certain
observations that allthough improvements
cost more than the estimate and the
contractor gave you a 35,000 for your um
estimated Home Improvement so therefore
you can conclude that your costing for
your home improvement will be more than
35,000 so there is certainty that your
costing for your home improvement will
be more than 35,000 that is why that is
deductive
resoning now let us have with George FIA
George FIA he was an H Hungarian
mathematician who immigrated to the
United States dur uh in
1940 so his major contributions is his
influential book which is entitled how
to solve it in the year of 1945 so Pula
is widely recognized for his work in the
field of ristics which are strategies or
techniques used to solve problems
wherein he gives us uh a four approaches
for us to to solve a word problem so
first he gave us understand the
problem we need to understand the
problem to identify what is
given what is needs to be found second
is we need to devise a plan remember
after understanding problem let us
determine how to approach the problem
using known strategies or methods the we
have now we we have a device plan so now
we can carry out the problem which which
is we can execute the plan and solve the
problem and after that after you answer
or carry out the problem you can review
and also
reflect by using the step for which is
look back so checking the solutions for
accuracy and reflect on the problem
solving process Pula uh work has had a
lasting impact on mathematics education
and the way problem solving is approach
in various Fields so now let uh here are
some ma problem solving strategies that
we can use for us to identify or how to
approach those word problem that we we
are going to encounter first we can look
for a pattern if you remember that we've
discussed the sequences
okay so we are looking for the pattern
for us to identify if we're going to
have um gen um geometric sequence or
arithmetic sequence by by looking their
common difference or their common ratio
and also we can have make an organized P
so by a word problem we can list all the
Givens for us to identify which formula
that we are going to use also we can
have guess in
check as you remember mathematics is a
trial and error so you can guess and
check if your solution is correct
accordingly and also you can make a
table which is for you to have
illustrative way to think about how you
are going to assess the problem itself
we have working backwards by checking
your your
answers by substituting the value of
your answer in your given problem so
that is working backwards use logical
reasonings wherein you are using um
inductive or deductive reasoning you are
going to use your critical thinking
skills here and also another strategies
that we can use draw a diagram in some
part of your your encountering word
problems you can draw for you to have um
a visualizations how the problem or how
to execute the problem and also number
eight solve a simpler problem nine read
the problem carefully and lastly create
the problem solving journals okay so
those my problem solving strategies I
hope this will help you to be more
effective to be more uh create in your
final answer and do or some strategies
that you
can work with your word problem okay so
that's all for today God bless you
everyone have a nice day have a great
day see you to the next video
