Question

For a project in your statistics class you decide to make a histogram of the salary data for players in the National Basketball Association (NBA). Since most of the players in the NBA earn the league minimum based on their years of service and a few superstars earn very high salaries in comparison, which of the following would most likely be a characteristic of your histogram?
a. Skewed-right
b. Skewed-left
c. Symmetric, with a central peak
d. Uniform

Answer 1

Answer:

b. Skewed-left

Step-by-step explanation:

The histogram will be expressed with the x-axis representing the salaries, in growing amount to the right. The y-axis will represent the relative or absolute frequency.

We know that most of the players earn the minimum league wage. Then, we will have a high frequency in the low salaries classes, at the left of the histogram. A few players earn very high salaries, so we will have a right tail with high values for the salaries a little frequency.

There is no symmetry in this histogram and it is not uniform, as there is no representative mean salary.

As most of the data will be close to the left side, we can conclude that the histogram will be skewed-left.
