Exam 1: Displaying the Order in a Group of Numbers Using Tables and Graphs

On the first exam in an introductory statistics class most students did very well and only a few did poorly. How would you describe the distribution of test scores?

An education researcher collects data on how many students are on scholarship at various local colleges. The researcher then makes a frequency table to summarize the data. The researcher is using a(n):

On a particular test of reading ability (in which high scores mean high reading ability), the distribution of adults is skewed to the __________ because most adults have fairly good reading ability, but a small number of people are nearly illiterate.

In a histogram, the horizontal dimension displays a:

When a distribution is heavy-tailed it means that:

A rectangular distribution, in addition to being symmetrical, would be an example of a(n): __________.

When a distribution is skewed to the right, it means that:

In a study of hospitalized psychiatric patients, the __________ of interest is how well the patients can take care of their rooms, as rated by the nurses on a scale of 0 to 7.

The histogram of a(n)__________ distribution has one of the bars higher than all the others.

The value of putting numbers into a frequency table is that:

All of the following are examples of rank-order variables EXCEPT:

Social scientists use frequency tables, histograms, or frequency polygons to show:

If all the values in a distribution have about the same frequency, it is called a(n):

Which of the following is supported by research cited in your text?

In a study of exercise behavior, a researcher found that the shape of the distribution of the number of hours exercised was __________ because one large group of people did not exercise at all while another large group all exercised approximately hours per week.

Several employees of a major corporation are rated for their degree of job satisfaction. If a particular employee's job satisfaction is rated 8 on a 20-point scale, 8 represents that employee's:

A frequency table is most likely to be included in a research article when:

Which of the following is an example of a nominal variable?

A test of social skills is administered to all professors at a local college. The __________ of a particular professor is 81.

A frequency polygon looks most like:
