Question

Calculate arithmetic mean from the following data 10, 14, 9, 8, 13, 7, 15, 12, 11, 16​

Answer 1

Answer:

Mean = 11.8, Median = 12, Mode = 14

Explanation:

Find the sum:

Sum = 10 + 15 + 14 + 13 + 18 + 11 + 9 + 8 + 14 + 6

Sum = 118

Find the mean:

Mean = Total / Number of items

Mean = 118 / 10

Mean = 11.8

Find the median:

Arranging them in ascending order

6, 8, 9 , 10, 11, 13, 14, 14, 15, 18

Median = (11 + 13)/2

Median = 12

Find the mode:

Mode is the item with the most frequent occurrence

Mode = 14 (which appeared twice)

Answer: Mean = 11.8, Median = 12, Mode = 14
