hey dear

here is your answer

Height in cm.


1) 30-40
2) 40-50
3) 50-60.
4) 60-70
5) 70-80
6) 80-90

no of plants

1) 4
2)3
3)8
4)11
5)6
6)8


in this we have to find mode

we use mode formula

mode formula is. -
mode = l + (f1 - f0)  \div (2f1 - f0 - f2) \times  height
by this solution are as follows

Here is the maximum class frequency 11

Class corresponding to the frequency is 40-50
so the modal class is 40-50

Modal class = 40-50 lower limit (L) of modal class = 40 class size (h) = 10

So,

frequency (f1) of modal class =11

frequency (f0) of class preceding the modal class =4

frequency (f2) of class succeeding the modal class = 10


Let us substitute these values in the formula

= 40+(11-4/10*11-4-10)*10. (10 is the height)


By simplying this

the answer is 2.6

Therefore the mode of above data is 2.6

hope it helps

thank you
