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.
