Question

here are ten numbers
​

Answer 1

Solution,

Given data=3, 7 , 2 , 4, 7, 5, 7, 1, 8, 8

a.Mode= 7 because it has more frequency in comparison to others.

b.Arranging the data in ascending order:

: 1,2,3,4,5,7,7,7,8,8

N(total number of items)=10

Median=(N+1/2)th item

= (10+1/2)th item

= (11/2)th item

= 5.5th item

Again,

5th item+6th item/2

= 5+7/2

=12/2

= 6

c. summation FX=52

N=10

Mean= summationfx/N

=52/10

=5.2

D. Range= highest score- lowest score

= 8-1

=7

Hope it helps

Good luck on your assignment

Answer 2

7+5/2=12/2=6

c .3+7+2+4+7+5+7+1+8+8/10=52/10=5.2

d .subtract from the bigger number the small number

8-1=7
