Question

find mode:class is 0-5,5-10,10-15,15-20,20-25,25-30,30-35.freqency is 10,15,30,80,40,20,5.​

Answer 1

Answer:

mode =L+(f¹-f⁰/2f¹-f⁰-f²)*h.

solve it after of ur own

Answer 2

Class...........frequency

* 0 - 5.............10

* 5 - 10............15

* 10 - 15...........30

* 15 - 20..........80

* 20 - 25.........40

* 25 - 30..........20

* 30 - 35..........5

Modal class...... 15 - 20

Modal class means the one with highest frequency.

Now F1 = 80

2F1= 2*80 = 160

F0= 30

F2=40

L=15

H = 5

Substituting in mode formula...

Mode = l + f1 - f0/ 2f1 - f2 - f0 * h

Do it yourself..... So it would be a practice.... I have given sufficient details/clues...
