North Heights HS is positively skewed, and Southview HS isnegatively skewed.

Answer 1

Given:

The distributions shown in graph.

Required:

Which statement correctly compares the shapes of the distribution?

Explanation:

Negative skew refers to a longer or fatter tail on the left side of the distribution, while positive skew refers to a longer or fatter tail on the right. These two skews refer to the direction or weight of the distribution.

So from graphs of distributions, we can check that North height HS is positively skewed and Southview HS is symmetrical.
