The descriptive statistics tries to capture the large set of observation along with giving us some ideas of the data that has been set so far. All the measures of central tendency like mean along with mode and median will come under this branch and they can distribute the data like normal distribution and standard distribution. In this type of statistics, data can be represented in the form of graphs that will help the users in understanding the experiment part.

Inferential Statistics-

This type of statistics involves drawing out the right conclusions from the statistical analysis which has performed under descriptive statistics. If the experiment is performed better in description statistics, then users will able to draw the right decision or conclusion for the above study.

Importance of Statistics in different areas

Statistics plays an important role in human life. This field

• Helps in finding out the existing per capita income
