Question

calculate mode and median of ci 0-10,10-20,20-30,30-40,40-50 and f 12,18,25,19,13​

Answer 1

Answer:

Step-by-step explanation:

ci         fi

0-10    12

10-20   18

20-30  25

30-40  19

40-50  13

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

modal class= 20-30 as it has highest frequency

so, l=20  ,  f1=25, f2=19, f0=18, h=10

mode =20 +(25-18/30-18-19)*10

        = 20 +(7/-7)*10

       =20-10

mode=10
