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

Answer:

12

Step-by-step explanation:

Mean is given by:

Mean= $\frac{Sum of data}{Number of terms }$

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= $\frac{192}{16}$

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.
