Step1: Count data - points

There are 3 values of 1, 5 values of 2, 2 values of 3, 2 values of 4, 4 values of 5.

Step2: Calculate the sum of products

Sum $S=(3\times1)+(5\times2)+(2\times3)+(2\times4)+(4\times5)=3 + 10+6 + 8+20 = 47$.

Step3: Calculate the total number of data - points

Total number of data - points $n=3 + 5+2+2+4=16$.

Step4: Calculate the mean

Mean $\bar{x}=\frac{S}{n}=\frac{47}{16}=2.9375$.

Answer:

$2.9375$
