Chapter 1: Q 19. (page 25)

Going to school Students in a high school statistics class were given data about the main method of transportation to school for a group of 30 students. They produced the pictograph shown. Explain how this graph is misleading.

Short Answer

Expert verified

The various keys do not correspond to the same number of people who use this mode of transport.

The pictogram's widths don't match the number of people in the key.

Step by step solution

01

Step 1. Given information.

The given pictogram is:

02

Step 2. Explanation.

With the provided pictogram, there are two major issues:

The first problem is that different keys correlate to different numbers of people. Because each pictogram represents a different amount of people using this mode of transportation, it will look that an equal number of people are using the bus as opposed to cycling when we just have one pictogram for each.

The second problem is that the pictogram's widths don't match the number of people in the key.

The width of the automobile pictogram, for example, is roughly two times that of the walk pictogram, despite the fact that they both correspond to two people.

Who studies more? Researchers asked the students in a large first-year college class how many minutes they studied on a typical weeknight. The back-to-back stemplot displays the responses from random samples of 30 women and 30 men from the class, rounded to the nearest 10 minutes. Write a few sentences comparing the male and female distributions of study time.

Enhancing creativity Do external rewards—things like money, praise, fame, and grades —promote creativity? Researcher Teresa Amabile recruited 47 experienced creative writers who were college students and divided them at random into two groups. The students in one group were given a list of statements about external reasons (E) for writing, such as public recognition, making money, or pleasing their parents. Students in the other group were given a list of statements about internal reasons (I) for writing, such as expressing yourself and enjoying wordplay. Both groups were then instructed to write a poem about laughter. Each student’s poem was rated separately by 12 different poets using a creativity scale. 26 These ratings were averaged to obtain an overall creativity score for each poem. Parallel dotplots of the two groups’ creativity scores are shown here.

Part (a). Is the variability in creativity scores similar or different for the two groups? Justify your answer.

Part (b). Do the data suggest that external rewards promote creativity? Justify your answer.
