To find the median for a frequency distribution, organize the data into a table, calculate cumulative frequencies, and use a formula.

To find the median for a frequency distribution, follow these steps:

Organize the data into a frequency table, with two columns: class intervals and frequencies.
Calculate the cumulative frequency for each class interval.
Identify the interval that contains the median value (usually the one with the highest cumulative frequency less than or equal to half the total frequency).
Use the formula (L + ((n/2) - F) / f) x w, where L is the lower boundary of the median interval, n is the total frequency, F is the cumulative frequency of the previous interval, f is the frequency of the median interval, and w is the width of the interval, to calculate the median.
