Question

how to find f from cf in statistcs

Answer 1

Technically, a cumulative frequency distribution is the sum of the class and all classes below it in a frequency distribution. All that means is you’re adding up a value and all of the values that came before it. Here’s a simple example: You get paid $250 for a week of work. The second week you get paid $300 and the third week, $350. Your cumulative amount for week 2 is $550 ($300 for week 2 and $250 for week 1). Your cumulative amount for week 3 is $900 ($350 for week 3, $300 for week 2 and $250 for week 1).
