Question

explain while solving?

Answer 1

in what format is that? .... I can't open it. can you post a photo ?

Answer 2

its a .doc file.its a word file.

Answer 3

see what I get !

Answer 4

@Kreshnik try this. (s)he uses the newer version of doc

Answer 5

hmm,could be cuz its not backward compatible with 03

Answer 6

its a he -_-

Answer 7

lol sorry, that's why i put (s)he lol

Answer 8

T = total frequency = last no. in the accumulated frequency =50, understand?

Answer 9

how do you calculate cumulative frequency?

Answer 10

It is given...

Answer 11

ah ok,so how would i get the values of m,p and q?

Answer 12

Neglect your question,
An easier example is like this
Group Frequency Cumulative frequency
1 10 10
2 22 (10+22) = 32
3 23 (32+23) = 55

Understand?

Answer 13

@nck93 Do you understand how cumulative frequency comes?

Answer 14

i get that concept,but i dont get it when you add letters into problem.

Answer 15

Alright , back to your question
Group Frequency Cumulative frequency
1 3 3
2 m 22
3 12 34
4 p q
5 5 48

For m, it is = 22-3 because 3+m =22

Answer 16

ah,now i get it.thanks.

Answer 17

3+m+12+p+5+2 =50
you have m, so solve p

and also q+5 = 48, so solve q

Answer 18

so t would be 2+T=50?

Answer 19

nope... T=50

Answer 20

why is that?

Answer 21

T is the total frequency, which is the maximum cumulative frequency you can see..

Answer 22

ah,i get it.thanks.

Answer 23

Welcome, any questions concerning this?

Answer 24

still a bit confused over solving p,but i'll get it it.i i get m,T and q,just not P yet.

Answer 25

p is one of the frequency and the sum of frequency is 50, so
3+m+12+p+5+2 =50
with m = 19, so you'll get p
