Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data.

This one hour 15 minutes video will help you to strengthen the basics of statistics and eventually helps you move a step further and learn more the topic.

There are variety of real life examples, solved problems and detailed knowledge about all the topics which are mentioned below.

In this video, we will study the numerical representatives of the ungrouped data, also called as measures of central tendency, namely Mean, Median and Mode.

Here, we will also study the measures of central tendency for the grouped data also.

We will extend this video in order to discuss the concept of cumulative frequency, the cumulative frequency distribution and how to draw cumulative frequency curves called as ogives.
