and they make it into  something which you can really use   having interpreted the data the data analyst can  then pass these insights on so that the company   can then make the most informed decisions  so you can think of data analytics as a   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   costs and to develop new and innovative products  and services in more specific terms data analytics   might be used to do the following to predict  future sales or purchasing behaviors for security   purposes to help and protect against fraud to  analyze the effectiveness of marketing campaigns   to boost customer acquisition and retention or  to increase supply chain efficiency so that gives   you a little bit of an overview of what data  analytics can be used for in the real world Step three let's dive into what a data  analyst actually does on a day-to-day basis   if you're thinking about becoming a data analyst  you're probably interested in the roles and   responsibilities that you'll have in the field  based on some real job ads here are some typical   roles and responsibilities that you'll have to  undertake as a data analyst manage the delivery   of user satisfaction surveys and report on  results using data visualization software   work with business line owners to develop  requirements define success metrics   manage and execute analytical projects and  evaluate results monitor practices processes   and systems to identify opportunities for  improvement translate important questions   into concrete analytical tasks gather new  data to answer client questions collating   and organizing data from multiple sources  design build test and maintain back-end code   establish data processes define data quality  criteria and implement data quality processes   work as part of a team to evaluate and analyze key  data that will

undertaking as a data analyst why   not search on job boards like linkedin indeed  and icrunchdata.com so that was step three   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   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   a must remember data analytics is about answering  questions and solving business challenges and that   requires some keen problem-solving skills data  analysts have a wide variety of tools at their   disposal and you'll need to know which one to use  and when you'll also need excellent communication   skills once you've harvested your data for  valuable insights it's important to share your   findings so that it benefits the business data  analysts work in close collaboration with key   business stakeholders and they may be responsible  for sharing their insights to those stakeholders   but also the entire company so if you're thinking  about becoming a data analyst you need to be   comfortable with this aspect of the job so that  summarises some of the key hard and soft skills   you'll require as a data analyst i hope this  has been a value obviously this isn't a broad   overview of the field at hand if you've enjoyed  this video we've got an in-depth article
