# What is the mean of the scores in Problem 8?

To determine

To calculate: The mean for set of test score 14,16,15,14,17,16,12,12,13,14.

Explanation

Given Information:

The given set of test score is 14,16,15,14,17,16,12,12,13,14.

Formula Used:

Mean of the data is,

x¯=Σ(xf(x))Σ(f(x))

Calculation:

Consider the data 14,16,15,14,17,16,12,12,13,14.

Then draw the frequency tables of the data as,

 Score (x) Frequency f(x) x⋅f(x) 12 2 24 13 1 13 14 3 42</
