Chapter 2: Problem 64

Create a dotplot that has at least 10 observations and does not have skew.

Short Answer

Expert verified
The dot plot representing the values {4, 5, 5, 6, 6, 6, 7, 7, 8, 8} is an example of a dot plot with at least ten observations and no skewness.

Step by step solution

01

Decide on Observations

First, select at least 10 numerical observations to represent in the dot plot. For example, the numerical observations might be {4, 5, 5, 6, 6, 6, 7, 7, 8, 8}.
02

Draw a Number Line

Draw a horizontal line, marking it with numbers that extend from the smallest to the largest values of your observation set. In this example, our number line would range from 4 to 8.
03

Represent Observations

Place a dot above the number line for each observation in the set. If multiple observations have the same value, place the dots for those observations directly above each other to form a vertical line.
04

No Skewness Verification

Confirm that the dot plot is not skewed. In other words, it should be more or less symmetrical, with similar numbers of observations on either side of the median. In our example, the median is 6 (mean of the fifth and sixth values), and there are equal (4) observations both left and right side of the median.
