What is Data analysis?

Data analysis is the process of examining and interpreting data in order to gain
insights, identify patterns, and draw conclusions. It involves using various
techniques and tools to organize, clean, transform, and analyze large datasets. Data
analysis is an essential component of many fields, including business, healthcare,
social sciences, and engineering.
There are different types of data analysis, such as descriptive analysis, which aims to
summarize and describe the characteristics of a dataset; exploratory analysis, which
seeks to identify patterns and relationships in the data; and inferential analysis,
which uses statistical methods to draw conclusions about a population based on a
sample of data.
Data analysis can be performed using a variety of tools, including spreadsheet
software, statistical software, and programming languages such as Python or R. The
ultimate goal of data analysis is to transform raw data into meaningful information

that can be used to inform decision-making and solve real-world problems.
