Question

Travel time (1.2) The dot plot below displays data on students’ responses to the question “How long does it usually take you to travel to school?” Describe the shape, center, and spread of the distribution. Are there any outliers?

Short answer

$80$and $90$appear to be outliers, Shape: right-skewed, Center: $15$, Spread: $15$

Step-by-step solution

Step 1. Given

Step 2. Concept

• Shape
• Center
• Spread

Step 3. Explanation

Because the majority of the data points are to the left and the tail is to the right, the shape is right-skewed.

Because the majority of the dots in the dot-plot appear above $15$, the center number is $15$

Spread $15$, because the gap between the mean and the graph's shortest endpoint is roughly $15$(0).

Outliers; There are outliers since the dot-plot has wide gaps in it. Outliers are dots that are far away from the rest of the dots, therefore$80$and $90$appear to be outliers. Therefore,$80$and $90$appear to be outliers, Shape: right-skewed, Center: $15$, Spread: $15$
