Question

2.
Find the mean of the data; 10.25, 9, 4.75, 8, 2.65, 12, 2.35
​

Answer 1

Solution :-

Arithmetic Mean = Sum of all observations/Number of observations

Observations = 10.25, 9, 4.75, 8, 2.65, 12, 2.35

Total number of observations = 7

Arithmetic Mean = (10.25 + 9 + 4.75 + 8 + 2.65 + 12 + 2.35)/7

⇒ 49/7

⇒ 7

Hence, arithmetic mean of the given data is 7.
