Median of Grouped Data

The video tutorial explains measures of central tendency, focusing on the median. It covers how to calculate the median in different data sets, including raw, ungrouped, and grouped data. The tutorial also discusses cumulative frequency distributions and how to handle less than and more than types. Practical examples are provided to illustrate the calculation of the median, including solving for missing frequencies.

What is the relationship between cumulative frequency and the total number of values in a data set?

In the example provided, what were the 50th and 51st observations used to calculate the median?

How can you convert a more than type cumulative frequency distribution back to continuous classes?

What steps are involved in finding the median when given a less than or more than type cumulative frequency distribution?
