Data analytics is a strategy-based science where raw data is analyzed to detect trends, answer questions, or draw conclusions from a large batch of data. Using various techniques, raw data is converted into a form that allows companies and organizations to analyze important metrics. Without data analytics, these metrics would likely be buried under a mass of information. This process helps companies increase their overall efficiency.  

Pursuing a career as a data analyst is a great choice if you're willing to keep learning and challenging yourself. In exchange, you'll enjoy a growing field of job prospects, as well as a lasting, high income career.

Types of Data Analysis

Based on the techniques used, data analysis can be classified into the following categories:

Process of Analyzing Data

The following are the steps involved in the data analysis process.  

  1. Data Requirement: First of all, you need to decide what kind of data you require. For instance, you might need the population of a particular area or the average income of a certain group of people.
  2. Data Collection: Data is collected whenever it’s necessary. Accuracy is a crucial part of collecting data because if it is not accurate, then the conclusion drawn will be wrong.
  3. Data Processing: This means that the gathered data has to be analyzed or organized. For example, you might choose to arrange the data in rows and columns in a spreadsheet.
  4. Data Cleaning: Not all of the data collected will be useful. Also, there are likely some errors in the data. At this stage, the data is cleaned and the errors are either removed or fixed. This step is important before analysis so that the outcome is accurate.
  5. Data Analysis: At this step, the data is analyzed and the conclusions are made. Various data analysis tools and techniques are used like data visualization, correlation, and regression analysis. Sometimes, there may still be some errors left even after data cleaning; these errors should be removed in this step.
  6. Communication: After analyzing the data, it is converted into an organized, simplified document. This document is used to take insightful actions and make data-backed decisions. For example, it might be presented in the form of charts, tables, or graphs.
