Chapter 2: Problem 63

Create a dotplot that has at least 10 observations and is right-skewed.

Short Answer

Expert verified
The resultant dotplot would visually show a right-skewed distribution through the selected data set {1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 5}. The plot would have at least 10 observations, and be skewed to the right, with a majority dots towards the right.

Step by step solution

01

Determine Data Values

Start by choosing at least 10 data points that form a right-skewed distribution. A right-skewed dataset could be {1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 5}. This data set consists of 12 observations with the distribution tails to the right, hence right-skewed.
02

Outline the Dotplot

Next, you would need to outline the plot. This plot comes with x and y axes. The x-axis represents the data values and the y-axis represents the frequency or number of occurrences of a data value.
03

Plot the Observations

Each observation from the data set will then be plotted along the x-axis. Every time a data point reoccurs, a dot is placed above the previous one. For instance, the value 2 reoccurs thrice so 3 dots will be plotted above the number 2 on x-axis.
04

Review the Dotplot

Finally, you would need to review the dotplot. It should visually demonstrate a right-skewed distribution. The 'body' of the distribution should be located at the left with fewer dots, and 'tail' at the right should have more dots.

Ideal Weight Thirty-nine students ( 26 women and 13 men) reported their ideal weight (in most cases, not their current weight). a. Explain why the distribution of ideal weights is likely to be bimodal if men and women are both included in the sample. b. Make a histogram combining the ideal weights of men and women. Use the default histogram provided by your software. Report the bin width and describe the distribution. c. Vary the number of bins, and print out a second histogram. Report the bin width and describe this histogram. Compare the two histograms.

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

Sleep (Example 2) An instructor asks a class of 120 students how many hours they slept during the previous night. What shape do you think this distribution will have? Explain.

Community College Applicants Applicants to California community colleges are asked to indicate one of these education goals at the time of application: transfer to a four-year institution, an AA degree, a CTE certificate, job retraining, or personal enrichment. In a group of 500 applications, describe a bar graph of these data that would have the least amount of variability. Also describe a bar graph that would have the most variability.
