Question

finding the mean and median
milams study group received test scores of 96, 91, 82, 99, 94, 92, 95, 92, and 80. find the mean and median scores.
the mean is
the median is

Explanation:

Step1: List all given scores

Scores: $96, 81, 82, 99, 94, 92, 95, 82, 80$

Step2: Calculate the sum of scores

$$\begin{align*} \text{Sum} &= 96 + 81 + 82 + 99 + 94 + 92 + 95 + 82 + 80\\ &= 801 \end{align*}$$

Step3: Compute the mean (average)

Mean = $\frac{\text{Total Sum}}{\text{Number of Scores}}$
$\text{Mean} = \frac{801}{9} = 89$

Step4: Order scores for median

Ordered scores: $80, 81, 82, 82, 92, 94, 95, 96, 99$

Step5: Find the median (middle value)

For 9 values, the 5th value is the median: $92$

Answer:

The mean is 89
The median is 92
