In the modern age, data analysis has crept up to the top of the Digital Transformation paradigm and Data Analyst is becoming one of the most important roles in the industry as they are involved in key business decisions and strategies because of their insights and reporting capabilities.
But what is Data Analysis? In simple words, Data Analysis is a process of extracting useful information from data using different Statistical and Mathematical methods. But Data Analysis alone cannot help. It is because after performing Data Analysis on some data, we usually store the information in CSV file, some databases, or in some other format and it is very difficult to read data from these formats, especially for non-technical people. Also, it is very unintuitive to read data from those files. To solve this problem, we perform Data Visualization. Data Visualization is the presentation of data in pictorial and graphical format. These pictorial and graphical formats are very easy to understand for even non-technical people.
To prove this point, let’s assume an excel sheet having thousands of rows of sales data. Now let’s say we just look at the data for 30 seconds, then someone asks a question like which product is giving maximum profit or which product is giving minimum profit, it will be very difficult to provide him with a satisfactory response as it is hard to get this type of information from those data just by looking at it.
