Q22. When constructing a frequency distribution, which of the following rules must be followed?

(a) The width of each class is equal to the lowest value in the data set.

(b) The midpoint of each class must be an integer.

(c) The number of classes must be an even number.

Q23. The rule of thumb for creating a frequency distribution is to divide the data into 5-15 classes. While larger numbers of classes allow for larger data sets, how do you know exactly how many classes to use?

(a) If in doubt about the number of classes, select 10 since it is the midpoint between 5 and 15 classes.

(b) Any number of classes between 5 and 15 is sufficient.

(c) Determine the width of the class interval, then calculate the number of classes.

(d) Select the number of classes that provides definition to the shape of the data.

Q24. The following numbers represent exam scores in an accounting class:

78, 93, 85, 81, 73, 96, 72, 86, 90, 85

(a) 10

(b) 4

(c) 3

(d) 5

Q25. In the above figure of wine imports into the United States, what three guidelines for developing good graphs have not been followed?

(a) Distorted data, unnecessary adornment, no scales for either axis.

(b) Distorted data, X axis not labeled, no title.

(c) Distorted data, unnecessary adornments, vertical axis not properly labeled.

(d) Unnecessary adornment, vertical scale does not begin at zero, no title.

Q26. Considering the various types of tables and charts introduced in this chapter, which table, chart, diagram or plot would you use to depict categorical data for two variables in a visual format?

(a) scatter plot

(b) contingency table

(c) pie chart

(d) side-by-side bar chart

Q27. The cumulative frequency for a particular class is equal to 35. The cumulative frequency for the next class will be _________________ .

(a) 35 minus the next class frequency.

(b) equal to 65.

(c) 35 plus the next class frequency.

(d) less than 35.

Q28. Which of the following would be most helpful in the construction of a pie chart?

(a) Ogive

(b) Frequency distribution

(c) Relative frequencies

(d) Cumulative percentages

Q29. The table above shows the frequency and relative frequencies for 7 groups of restaurant meal prices. How was the value of 0.36 obtained for the relative frequency of meals costing \$32 but less than \$40?

(a) The number of data points is 50, so divide 18 by 50.

(b) (18 x 2)/100 = 0.36.

(c) The midpoint of the class is \$36, so divide 36 by 100.

(d) (18/100) x 2 = 0.36. Q30. The highest bar in a histogram represents?

(a) The class with the lowest relative frequency.

(b) The class with the highest cumulative frequency.

(c) The class with the lowest frequency.

(d) The class with the highest frequency.
