Question

On a survey, students reported how many minutes it takes them to travel to school. Here are their responses. 10,13 ,16 5,4 ,14 , Find the mean travel time for these students.

Answer 1

Mean travel time = 10.33 minutes

Explanation:

The mean of a distribution is a measure of central tendency that shows the centre of a set of data. Mathematically, it is represented as:

Mean = Sum of the terms ÷ Number of terms

Mean = (10 + 13 + 16 + 5 + 4 + 14) ÷ 6

Mean = 62 ÷ 6 = 10.33

∴ Mean travel time = 10.33 minutes

N:B 10.33 minutes = 10 minutes + 0.33 minutes

converting 0.33 minutes to seconds

1 minute = 60 seconds

∴ 0.33 minute = 60 × 0.33 = 19.8 seconds

∴ Mean time = 10 minutes 20 seconds
