   Frequency Distribution. Find the Midpoints of the Frequency Table. Class Frequency 2 − 10 1 11 − 19 3 20 − 28 9 Class Frequency 2 - 10 1 11 - 19 3 20 - 28 9. The lower limit for every class is the smallest value in that class. On the other hand, the upper limit for every class is the greatest value in that class.

   Step 1: Construct the cumulative frequency distribution. Step 2: Decide the class that contain the median. Class Median is the first class with the value of cumulative frequency equal at least n/2. Step 3: Find the median by using the following formula: ⎛ n ⎞ ⎜ - F ⎟. e d i a n = L + 2. ⎜. ⎟ i. ⎜ f. m ⎟. Where: ⎝ ⎠. = the total frequency.
