Median Calculation for Grouped Data by wendz is a document available to read on EtoBox.

1. To find the median of grouped data, first calculate the total number of observations (N). 2. Divide the data into classes and calculate the cumulative frequency for each class. 3. Identify the class where N/2 lies as the median class. 4. The median is the lower limit of the median class plus the proportion of the class size between N/2 and the cumulative frequency before the median class.
