Question 1

When using interval data, one cannot
A) set up inequalities.
B) form differences.
C) divide.
D) do any of these.

Accepted Answer

Interval data allows for the setting up of inequalities and forming differences, but it does not have a true zero point, making division operations inappropriate because ratios between numbers are not meaningful.

Question 2

When using ratio data, one cannot
A) set up inequalities.
B) form differences.
C) divide.
D) can do any of these.

Accepted Answer

Ratio data supports all mathematical operations including setting up inequalities, forming differences, and dividing because it has a meaningful zero point that allows for the calculation of ratios.

Question 3

A type of data that does not allow inequalities to have meaning is _______ data.
A) nominal
B) ordinal
C) interval
D) ratio

Accepted Answer

Nominal data is categorical and does not have a meaningful order or ranking, so inequalities (like greater than or less than) do not apply.

Question 4

A type of data in which zero indicates the absence of a certain property is _______ data.
A) nominal
B) ordinal
C) interval
D) ratio

Accepted Answer

Ratio data not only allows for the identification of differences between quantities but also has a meaningful zero point that indicates the absence of the quantity being measured.

Question 5

Measurements of height involve which kind of data?
A) nominal
B) ordinal
C) interval
D) ratio

Accepted Answer

Height measurements are ratio data because they have a true zero point and the differences between measurements are meaningful.

Question 6

If the apartment numbers in a large building are looked upon as data, they would fall into the _______ category.
A) nominal
B) ordinal
C) interval
D) ratio

Accepted Answer

Apartment numbers are used to identify or categorize different units without implying any order, rank, or measurable difference between them, which is characteristic of nominal data.
