Question

find the mean of:
5 37 27 4 17 19 5 39
26 30 1 6
mean =

Explanation:

Step1: Count the number of values

There are 12 values: 5, 37, 27, 4, 17, 19, 5, 39, 26, 30, 1, 6.

Step2: Calculate the sum of values

Sum = \(5 + 37 + 27 + 4 + 17 + 19 + 5 + 39 + 26 + 30 + 1 + 6\)
= \(5+37=42\); \(42+27=69\); \(69+4=73\); \(73+17=90\); \(90+19=109\); \(109+5=114\); \(114+39=153\); \(153+26=179\); \(179+30=209\); \(209+1=210\); \(210+6=216\)

Step3: Calculate the mean

Mean = \(\frac{\text{Sum}}{\text{Number of values}}=\frac{216}{12}=18\)

Answer:

18
