Takeaways
- 📊 Use Google Sheets to calculate statistical measures like mean, median, mode, and range with ease.
- 🔍 Insert functions in Google Sheets by going to 'Insert' > 'Function' or by typing '=' and starting to type the function name.
- 📈 To find the mean, use the 'AVERAGE' function and select the range of cells you want to calculate the mean for.
- 📋 Copy and paste the mean formula to other columns or sheets to quickly calculate additional means.
- 🔢 For the median, use the 'MEDIAN' function and select the appropriate cells to find the middle value of the dataset.
- 📑 After performing all necessary calculations, sort the data to identify the mode and range.

- 🔑 Remember to sort the data last after all calculations are complete to avoid disrupting the data's original order.
- 🔍 The 'MODE' function can also be used to find the most frequently occurring number in a dataset.
Q & A
What is the main topic of the video?
-The main topic of the video is teaching viewers how to use Google Sheets to calculate statistical measures such as mean, median, mode, and range.
How does the video suggest finding the mean in Google Sheets?
-The video suggests inserting a formula for the mean by either going to 'Insert' then 'Function' and selecting 'Math' or 'Statistical', or by typing an equal sign followed by 'average' and selecting the range of cells to calculate the mean.
What keyboard shortcut is used to copy a formula in Google Sheets according to the video?
-The video mentions using 'Ctrl C' to copy a formula in Google Sheets.
How can you apply the copied formula to other columns or sheets in Google Sheets?
-After copying the formula with 'Ctrl C', you can paste it into other columns or sheets as needed by using the 'Paste' option or the 'Ctrl V' keyboard shortcut.
What is the recommended method for finding the median in the video?
-The video recommends finding the median by inserting a formula or typing an equal sign followed by 'median' and then selecting the range of cells to calculate the median.
Why should sorting data be done at the end of data analysis in Google Sheets?
-Sorting data should be done at the end of data analysis because it rearranges the data, which could disrupt any previously calculated relationships or associations between data points.
How does the video demonstrate sorting data in Google Sheets?
-The video demonstrates sorting data by highlighting the numbers to be sorted, going to the 'Data' tab, and selecting 'Sort range' to sort the data in ascending order from smallest to largest.
What is the easiest way to calculate the mode according to the video?
-The easiest way to calculate the mode, as per the video, is to sort the data and visually identify the most common number, or by using a formula that calculates the mode.
How can you calculate the range in Google Sheets after sorting the data?
-After sorting the data, the range can be calculated by subtracting the smallest value from the largest value, or by using a formula that automatically calculates the difference between the maximum and minimum values in a given range.
What is the video's overall advice for using Google Sheets formulas?
-The video advises using Google Sheets formulas to automate and expedite the process of calculating statistical measures, thus making the task easier and more efficient.

so in this video I'm gonna go through
how to use Google sheets to calculate
things like mean median mode and range
and to make it really quick and easy on
yourself so that you don't have to do a
lot of work you can pretty much just set
up formulas so for example what you
could do in your spreadsheet is add
topic titles like mean and median um one
of the easiest ways to find a mean is to
just insert a formula so you can go
insert function and we can go to math or
we can go to statistical and and you're
not that I mean that you will find
average the other thing that you can do
is if you put an equal sign in the box
and then start typing so you can already
see if you start typing the word average
it will come up and we just want a
normal average and then all you have to
do is drag the cells that you want to
find the average so for example we're
gonna go from here all the way to here
and it will send the formula for you and
all you have to do is close the bracket
and then when you hit enter your mean or
your average will already automatically
be populated and you can also copy that
so hit ctrl C to copy and you can paste
it into the other columns now I know
that you don't have to do it for all of
the columns but you could paste it into
as many columns as you want and you can
be pasting that into all of your other
sheets as well so for example if we
wanted to find the mean on the hi column
for everyone again we we could type in
the word mean so that we remember what
it is in this box we could go insert and
then math or insert statistical and you
will see average or you can hit the
equal sign and start doing it and so
here what you want to do again find the
first one and scroll all the way to the
last one and hit enter and then there is
your average for everyone in the grade
and again you can copy that
and paste it into the other columns to
find the other averages if you would
like to so likewise for median same
thing we could go insert and a formula
or if we hit equals and just typing the
word median we will see it and then we
can just scroll for the values that we
want
oh sorry something went wrong here so
again equals start typing median and you
can select that it's actually now gonna
suggest the values that you want so
double check that that's correct and if
you've got that hit enter and then again
you can just copy and paste that into
the other columns as you would like them
to be able to get your mode and your
range the easiest thing to do is to sort
the data and to sort the data what you
can do is highlight all of the numbers
that you want to sort and if you go to
the column two tab at the top data you
can sort in different ways and so one of
the ways that we're gonna do is we're
gonna sort the range it's a it's this is
telling us sort the range in column B
from A to Z and eight to said means in
alphabetical order or in this case
because it's not letters it's going to
sort them in numerical order from
smallest biggest if I click that I've
now sorted the data now make sure that
you don't do this step until you've used
the data any way that you want because
what its gonna do it's gonna change the
data around so again we're gonna
highlight and we're gonna sort that so
it's gonna change the information and
change so we had a particular person's
height was matched with their arm span
that's now changed so make sure you're
not doing this till the end but what you
can see now is you can see this also and
you calculate by subtracting in your
head or on your calculator you can also
quickly glance and see the mode um I
also believe I think you can also
find the mode if you get equals and type
the word mode and then again select so
the mode you can use a formula for if
you want and so there's the mode right
there or you can just sort it and look
at the most common number but sorting
will be very useful when you're trying
to calculate the range because it
automatically will sort from the
smallest to the biggest so use the
Google sheets formulas to your advantage
to make things a lot faster for yourself
in terms of making the calculations for
the measures of central tendency
