Question

Calculate mean deviation of the following scores:

3,4,5,6,7,8,9,10​

Answer 1

Step-by-step explanation:

Add them all

3+4+5+6+7+8+9+10=52

No of observation=8

so,

52/8=6.5

So the mean of the score is 6.5

hope it will help u

Answer 2

Answer:

Mean deviation for the given set is 2.

Step-by-step explanation:

Step 1: Calculate mean:

3+4+5+6+7+8+9+10 = 52

Number of values= 8

Mean = Sum of the values/ number of values

= 52/8 = 6.5

Step 2: Calculate sum of deviation from the mean

Ignore the negative sign

3-6.5= 3.5

4-6.5=2.5

5-6.5=1.5

6-6.5=0.5

7-6.5=0.5

8-6.5=1.5

9-6.5=2.5

10-6.5=3.5

Sum of the deviation= 16

Mean deviation = Sum of the deviation/number of values = 16/8 =2
