Question

10.

Absolute (actual) frequency distribution is

	a tabular summary of a set of data showing the relative frequencies
	a graphical form of representing data

	a tabular summary of a set of data showing the actual number of items in each of several nonoverlapping classes
	a graphical device for presenting categorical data

11.

If several frequency distributions are constructed from the same data set, the distribution with the widest class width will have the

	fewest classes
	most classes

	same number of classes as the other distributions since all are constructed from the same data
	I do not see the correc answer

12.

In an absolute cumulative frequency distribution, the last class will always have a cumulative frequency equal to

	one
	100%

	the total number of observations in the data set
	None of these alternatives is correct.

13.

In a cumulative percent frequency distribution, the last class will have a cumulative percent frequency equal to

	one
	100

	the total number of elements in the data set
	None of these alternatives is correct.

14.

In a cumulative frequency distribution, the first class will have a cumulative frequency equal to

	The same as its own frequency
	n or sample size

	the total number of elements in the data set
	I do not see the right answer

15.

In constructing a frequency distribution, as the number of classes is decreased, the class width

	decreases
	remains unchanged

	increases
	I do not see the right answer

16.

In constructing a frequency distribution, the approximate class width is computed by

	(largest data value - smallest data value)/number of classes
	(largest data value - smallest data value)/sample size

	(smallest data value - largest data value)/sample size
	largest data value/number of classes

17.

The difference between the lower class limits of adjacent classes provides the

	number of classes
	class limits

	class midpoint
	class width

18

The relative frequency of a class is computed by

	dividing the frequency of the class by N
	dividing the frequency of the class by the number of classes

	dividing n by N
	dividing the frequency of the class by n

19

The sum of the relative frequencies for all classes will always equal

	the sample size
	the number of classes

	one
	any value larger than one

20

The total number of data items with a value less than the upper limit for the class is given by the

	absolute frequency distribution
	relative frequency distribution

	absolute cumulative frequency distribution
	cumulative relative frequency distribution
