Question

Find the mean of the following data:
10, 16, 15, 14, 8, 21, 10, 5, 19, 18, 4, 5, 16, 12, 10, 9

Answer 1

12

Explanation:

Mean is given by:

Mean=
`(Sum of data)/(Number of terms )`

Here Sum of data= 10+16+15+14+8+21+10+5+19+18+4+5+16+12+10+9

Sum of data= 192

And,

Number of terms= 16

So,

Mean=
`(192)/(16)`

Mean= 12

Answer 2

The answer: 12


The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
