Median from a frequency table is when we find the median average from a data set which has been organised into a frequency table.
To estimate the number of minutes late for each group, create a midpoint column. To find midpoints, add the start and end points and then divide by 2.
For grouped data, a frequency distribution is required to find the median and is done by using the formula. Median = l + [(n/2−c)/f] × h. ☛Also Check:
