this is where data analytics comes in data  analytics is the process of analyzing raw data  

so that we can pull out insights which are useful  to companies these insights are super important to  

drive smart business decisions what a data analyst  does is they take all this complex jigsaw of data  

they take it out and they make it into  something which you can really use

kind of business intelligence used to solve  problems and challenges that every company has  

it's all about finding patterns in the data which  can tell you something useful or relevant about  

the business operations so for instance how  customers engage with a particular product or  

employees engage with a particular tool armed with  the insights of data companies are then able to  

make better decisions about their audience company  as a whole and the industry in which they work in

Step one we looked at what Data Analytics  actually is in step two we're going to look  

at how data analytics is used so what does data  analytics actually look like in action and how is  

it used in the real world so the fact is data is  everywhere so it actually has an infinite amount  

of uses across all kinds of businesses and  organizations globally broadly speaking data  

analytics is used to make faster and better  business decisions to reduce overall business

it was just a broad overview of what you  can expect to be doing as a data analyst

So now we've looked at data analytics as a role  we're now going to go into the process of data  

analysis so now we're going to outline  the five main steps a data analyst would  

take when approaching a new project step one  define the questions that you want to answer  

you need to answer why you're conducting this  analysis and what questions and answers you  

need to find at this stage you'll take a clearly  defined problem and then you'll make a hypothesis  

or research question that you can go on and  answer you'll then need to identify what types  

of data you'll need but importantly where it  will come from for instance a business problem  

might be that customers aren't subscribing to  a paid membership once that free trial ends  

your key question can then be what kind  of strategies can the business implement  

to retain their customer base step two would be  to collect this data with a clear question in mind  

you're ready to start collecting that data data  analysts will usually gather data from primary  

sources or internal data that the company already  has such as CRM software or email marketing tools  

they may tend to secondary or external sources  such as open data sources so this can include  

data from government portals tools like  google trends but also data from international  

organizations like the world health organization  so step three you need to clean scrub that data  

once you've got that data you need to prepare  it and ready it for analysis your original data  

might include duplicates anomalies or missing data  which could distort how the data is interpreted  

these all need to be removed data cleaning can be  a manual task and it can take some time but it's  

crucial if you want to get the right business  insights step four is to analyze the data now  

for the actual analysis how you analyze the data  will depend on the question that you're asking  

and the kind of data that you're working  with but some common techniques include  

regression analysis cluster analysis and time  series analysis to name just a few we're going to  

go into these analysis terms much deeper in future  videos but if you have any specific questions now  

drop us a comment in the comments below moving  on to step 5 we need to interpret and share the  

results the final step in this process is where  data is turned into valuable business insights  

depending on the type of analysis conducted you'll  present your findings in a way that others can  

understand in the form of a chart or a graph for  example at this stage you'll be able to say what  

the data analysis actually shows you in regards  to your initial question or business challenge  

and you'll collaborate with key stakeholders  on how to move forward this is a great moment  

to reflect and look at the limitations of your  data and what further analysis might be conducted  

rounding off step four we're going to move  on to the next step what skills you need  

to actually become a data analyst in addition to  the role description and the processes that we've  

described so far data analysts are also expected  to demonstrate certain skills and abilities  

here are some of the most important hard and soft  skills that you'll need to become a data analyst

of their time crunching numbers so you'll need to  have a mathematical brain you'll have to have some  

working knowledge of programming languages such  as python oracle and sql data analysts rely on  

a number of programming languages to carry out  their work this may seem daunting at first but  

it's nothing that can't be learned over time with  practice you'll also need an analytical mindset  

it's not just about crunching the numbers and  sharing your data sometimes you'll need to dig  

deeper to understand really what's going on  it's all in the name an analytical mindset is
