The mean of the data is 5 hours

The Mean of a set of data can be obtained by dividing the sum of the data by the number of data i.e

$Mean = \frac{Summation of data }{number}$

With the above formula, we can obtain the mean of the data as follow:

Sum of data = 2 + 5 + 3 + 5 + 1 + 4 + 6 + 12 + 2 + 6 + 4 + 1 + 2 + 6 + 2 + 3 + 10 + 10 + 8 + 7

= 99

Number of data = 20

Mean =?

$Mean = \frac{Summation of data }{number of data}\\\\Mean = \frac{99}{20} \\\\$

Mean = 5 hours

Therefore, the mean of the data is 5 hours
