Question

find the mode of the following data


class interval frequency
0 - 10 16
10 - 20 13
20 - 30 6
30 - 40 11
40 - 50 27
50 - 60 18

Please its urgent

Answer 1

Please help me someone

Answer 2

sorry the modal class is 40-50, but how are we to tell what value in particlular (i'm getting punch--sorry for the previous post)

Answer 3

Let me tell you that for calculating mode of a grouped data

the formula is

M = l + (f1 - f0)/(2f1 - f0 - f2) * h

here,

l = lower limit of modal class

f1 = frequency of modal class

f0 = frequency of class preceeding modal class

f2 = frequency of class succeeding modal class

h = size of modal class

Now you only have to put the values.

Answer 4

My answer is 46.4

but

the book says it is 46.1

Answer 5

kusha, check this out... watch from 1:59 to 3:53

i have never hear of getting the mode from interval data, maybe your calculation is an approximation?

Answer 6

thanks for the video but this is the formula given in our text book and we have to use the formula for finding the mode.

Answer 7

i think it must be an approximation

Answer 8

yes it may be
but can you kindly calculate using the formula . I want to check my answer. Please

Answer 9

ok, gimme a minute

Answer 10

ok

Answer 11

I Double checked using your formula and ended up with:

40+(160/25)
46.4...

... Maybe you misread one of the datas? did you double check those points with the book

Answer 12

i get 46.4 same as you do

Answer 13

yes i did it.

thanks everyone, i think the book has misprinted it.

thank u all

Answer 14

the problem is sloppy from the beginning, the class intervals should be more precise, they should probably be half open intervals. in practive you might stop at .5 before the next integer.. if that were the case, that the h=9.5 then you get your 46.1 )actuallu 46.08

Answer 15

Got it ?

Answer 16

well m<1 refers to the measure of angle 1.

Answer 17

where as <x means angle formed by the rays intersecting at point at x
