Data Analysts search and extract relevant data for their organizations. After extracting data, they perform exploratory data analysis to understand it and make it in a structured form for Data Scientists to build Machine Learning models.

Use Case: Analysis of Data in the Healthcare Sector

Healthcare is one of the sectors highly benefitted by data analysis methodologies. Patients’ data generated by medical organizations are in quintillion bytes. To utilize such huge amounts of data, they need to convert the raw data into a properly structured form to understand it efficiently. Here comes the role of Data Analysts.

Data Analyst’s responsibilities are the extraction of the data from data warehouses and preparing it for analysis. At first, the extracted data is in the raw form, on which operations such as manipulation and visualization will yield inconsistent results. To make the data structured, Data Analysts perform various techniques to make it ready for use. You can see the below image that shows the form of well-organized and structured data.

Below are a few of the Data Analysts roles and responsibilities to convert data into a structured form:

• Classifying data as per rows and columns
• Removing redundant and non-essential rows and columns
• Eliminating null values
• Categorizing the values of columns according to data types (e.g., male, female, true, false, etc.)
• Converting the data into a readable format

Once the data is ready, it is given to Data Scientists for manipulation, visualization, and predictive analytics. The analysis of data by data scientists in the healthcare sector helps gather information related to drug requirements, ventilators, and other facilities. It also helps manage doctors’ availability, vacant rooms, emergency wards, and more. Automated systems built using healthcare data enhance the healthcare management system. Finally, any creation of automation technology starts from the data analysis and preparation performed by a Data Analyst. Thus, Data Analyst roles and responsibilities help the organization in business analysis.
