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

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

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

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
you'll need to have some mathematical and statistical ability data analysts spend a lot
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
