Question

Using the given set of numbers find the mean (rounded to the nearest tenth), median,mode and range: 18,19,16,18,14,17,18 and 15

Answer 1

• Mean = 16.9
• Mode = 18
• Median = 17.5

Explanation:

Given data:

• 18, 19, 16, 18, 14, 17, 18, 15

The data in the ascending order:

• 14, 15, 16, 17, 18, 18, 18, 19

The mean:

• (14 + 15 + 16 + 17 + 18*3 + 19)/8 = 16.9 (rounded)

The median:

• (17 + 18)/2 = 17.5 (the average of middle terms)

The mode:

• 18 (the most repeated number)
