Question

commulative frequency graph aur OGIVE same hota h kya??

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). Cumulative frequency distributions can be summarized in a table.




This table shows the frequency of hair colors for a population sample. If you add up all of the frequencies for the ?, you get a total of 41:
15 + 10 + 16 = 41.

What is a Cumulative Frequency Distribution used for?

Why would you want to use a cumulative frequency distribution? There are a couple of main reasons:

You want to check that your math is correct. By adding up all of the numbers and comparing it to your sample size, you know you’ve included all your data. For example if your sample size was 44 in this case, you’d know by the cumulative frequency distribution that you’re missing one piece of data.You’re interested in studying a population to find out a “more” or “less” question. For example, you’re thinking of opening a bargain grocery store and you want to know how many people in a particular geographic area spend up to $6000 per person per year in groceries. Your table might look like this:
