Romashka-Z-Leto [24]

Answer:

a) Mean - 10

b) mode - 9

c) Median - 9

d) SD - 2.708

Explanation:

A) Mean is the average of a given set of number in which the sum of all the number is divided by the number of entries

Thus, mean is equal to

\frac{9+12+7+15+8+9+10}{7} \\= \frac{70}{7} \\= 10

B) Mode is the most common number in a given series

Thus, mode is equal to 9 as it has appeared twice

C) Median

Number are arranged in ascending order

7, 8, 9, 9, 10, 12, 15

The middle number is the median i.e 9

D) Standard Deviation

Formula is square root of sum of (X - mean )^2 divided by N-1

(9-10)^ 2+ (12-10)^2 + (7-10)^2 + (15-10)^2 + (8-10)^2+ (9-10)^2+ (10-10)^2\\= 1 + 4+ 9+ 25+ 4+ 1+ 0\\= 44

\sqrt{\frac{44}{7-1} } \\= 2.708
