Question

the table below shows a students quiz scores on four quizzes.
find this students mean quiz score

Explanation:

Step1: Calculate the sum of scores

$$12 + 16+15 + 16=59$$

Step2: Calculate the mean

The number of quizzes \(n = 4\). The mean formula is \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). So \(\bar{x}=\frac{59}{4}=14.75\)

Answer:

\(14.75\)
