Answer 1

Explanation

We are given the following:

$80,68,77$

We are required to determine the following:

• Mean

,

• Median

- First, we arrange the data given in ascending (least to greatest) order. We have:

$68,77,80$

We know that the mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

Therefore, we have:

$\begin{gathered} Mean=\frac{68+77+80}{3} \\ Mean=\frac{225}{3} \\ Mean=75 \end{gathered}$

Hence, the mean is:

$Mean=75$

Also, we know that the median is the middle number in a sorted, ascending or descending, list of numbers.

Therefore, we have:

$\begin{gathered} 68,77,80 \\ Middle\text{ }number=77 \end{gathered}$

Hence, the median is:

$Median=77$
