What Is a Data Analyst?
A data analyst is a data science expert who collects, analyzes, and makes sense of large datasets using advanced tools. The information collected by data analysts is typically used for making predictions or significant decisions to boost efficiency in an organization.
Data analysts combine practicals and theories to deliver data-driven insights to an organization. They consider internal and external factors in data analysis. As a data analyst, you will also design algorithms for automated data manipulation.
What Does a Data Analyst Do?
Data analysts across industries might manipulate different datasets, but the overall job description is typically the same. The three tasks listed below are the most common data analyst duties.
Creates Performance Indicators
A data analyst develops performance indicators like KPIs, also known as key performance indicators. KPIs are made up of quantifiable measures to determine a company’s performance over time. You may be required to develop performance indicators for individual departments within the organization.
Some other essential performance indicators you may be required to work with are the client retention rate (CRR) and profit margin (PM). The company will use your performance indicators to improve client and employee satisfaction while balancing profitability.
A considerable part of your job will involve data visualization. This is simply making graphical illustrations of your data to present to others. Visualization makes it easier to spot trends and understand patterns.
Most data analysts use column, line, area, and scatter charts, plus bar graphs, for data visualization. The option you choose should depend on the datasets you are trying to illustrate and the audience you wish to address. Just make sure that you opt for the most efficient technique.
Collaborates with Others
As a data scientist, department heads will depend on your analysis to gauge how the department is doing. In big companies where roles are defined clearly, data analysts work closely with data scientists and data engineers. They also provide valuable feedback to product managers.
At regular intervals, you might make presentations to stakeholders or provide the data used for making these presentations. Significant decisions on how resources should be dispersed are made based on the findings of the data analyst. You should have good communication skills for this position.
Data Analyst Education Pathways
You can get all the education you need to become a data analyst from a university or data science bootcamp. However, if you prefer to train yourself, massive open online courses (MOOCs) are a great resource as well.

Top Data Analyst Skills
Technical skills will help you excel as a data analyst, and most can be developed on your terms. These skills include statistics, proficiency in Microsoft Excel, and data mining. Read below to learn more about the top data analyst skills.
As a data analyst, you will need to use statistics during your work. Therefore, you should learn as much as you can about descriptive statistics and inferential statistics. The latter is used to draw conclusions from datasets after analysis, while the former is used to summarize data before major analysis has been completed.
Coursera has a host of descriptive statistics courses you can use to learn on your own. It also offers courses on inferential statistics. Udemy and edX are other websites you can search for courses on both subjects.
As basic as this seems, proficiency in Microsoft Excel is a must for every data analyst. It allows you to simplify raw data into spreadsheets in readable formats that anyone can understand. Then, when you need to make complex calculations, you can automate the spreadsheet software program to do it for you.
All you need to master Microsoft Excel is a laptop. The application comes with tutorials that will help you get familiar with the program. In addition, you can take free Excel classes online if you need further guidance.
Data Mining and Examination
Data mining is an essential step in the data analysis process. It includes extracting insightful patterns from large and often unstructured datasets using all the tools at your disposal.
Data examination isn’t limited to what you can learn at a school or online. As an individual, you need to be a good observer who pays attention to detail. It doesn’t matter if you’re using automated tools or not. You still need to have a keen eye for spotting discrepancies.
