$4$ , $6$ , $16$

Step 1

The mean of a set of numbers is the sum divided by the number of terms.

$μ = \frac{4 + 6 + 16}{3}$

Step 2

Simplify the numerator.

Step 2.1

Add $4$ and $6$ .

$μ = \frac{10 + 16}{3}$

Step 2.2

Add $10$ and $16$ .

$μ = \frac{26}{3}$

Step 3

Divide.

$μ = 8.\overline{6}$

Step 4

The mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.

$μ = 8.7$

Step 5

Arrange the terms in ascending order.

$M e d i a n = 4, 6, 16$

Step 6

The median is the middle term in the arranged data set.

$M e d i a n = 6$

Step 7

Since the mean is greater than the median, the data set is positively skewed.

Positively Skewed
