Question

1. (l2) select the best word that describes the shape of the data set shown in the histogram below :

a. skewed left
b. uniform
c. skewed right
d. symmetric
histogram of arrivals

Explanation:

In a skewed - left distribution, the tail extends to the left. In a uniform distribution, the bars have approximately equal heights. In a skewed - right distribution, the tail extends to the right. In a symmetric distribution, the left and right sides are mirror - images of each other. Looking at the histogram, the left side is more compact and the right side has a longer tail, so it is skewed right.

Answer:

c. Skewed right
