Question

Help please?

Answer 1

So to find frequency we see HOW many times it has appered! okay?

Answer 2

5,6,9,3,1 how do i find the %

Answer 3

Then to find RELATIVE FREQUENCY
We find the percentage RELATIVE TO THE OTHERS!

Here A's relative frequency = No. of A's/the total number of observations
And that you mulyiply by hundred to find %

Answer 4

So here A = 3 * 100/24 = 300/24 = 12.5%
Getting me? :)

Answer 5

wait A is 5..

Answer 6

so 5/24*100

Answer 7

I see only 3 A's!!

Answer 8

@nslesin ?

Answer 9

my bad lol

Answer 10

so 3/24*100

Answer 11

YES!! :)
Similarly do ALL like that got it? :D

Answer 12

i got 12.5%, 33.3%, 37.5%, 33.3%, 4.2%

Answer 13

how do i do the cumulative frequency?

Answer 14

I don't think your answers are ACCURATE!
Check the calculations okay?
Because it SHOULD add autpo 100% :)

Answer 15

3/24*100= 12.5
8/24*100= 33.3
9/24*100=37.5
3/24*100= 12.5
1/24*100= 4.2

Answer 16

So basically Cumulative frequency puts the total in the last in an orderly data!
You will learn later in Statistics!! :)
Understood what I said? :D

Answer 17

Yeah and YOU ARE RIGHT!! :D

Answer 18

Cumulative frequency is defined as a running total of frequencies. The frequency of an element in a set refers to how many of that element there are in the set. Cumulative frequency can also defined as the sum of all previous frequencies up to the current point.

Answer 19

total cumulative frequency is 81?

Answer 20

See the total CF = 24
BECAUSE IT GIVES US THE TOTAL DATA!!
That means the total number of observations in data!
Cumulative frequency is defined as a running total of frequencies. [REFER TO MY DIAGRAM]
:)

Answer 21

You don't just add up the cumulative frequency for the total?

Answer 22

No you STOP when you get the total amount!
Understood? :D

Answer 23

see where it says total on the bottom then cumulative frequency what is that?

Answer 24

So what is that cumulative frequency

Answer 25

24 in this case!
Remember 'Cumulative frequency is defined as a running total of frequencies.'
Got it? :)

Answer 26

so like this?

Answer 27

YES!! :D

Answer 28

so it will always be the same as the total frequency..
