M2L2: Measurement

Question 1

is the process of assigning individuals, objects, or events to categories according to certain rules.

Answer 1

Measurement

Question 2

state that “the categories used to measure a variable make up a scale of measurement, and the relationship between the categories determine different types of scales

Answer 2

Gravetter and Wallnau (2019)

Question 3

weakest level of measurement where names, symbols or numbers are used simply for classifying subjects or categorizing subjects into different groups

Answer 3

Nominal (classificatory) scale or level

Question 4

contains the properties of the nominal scale, but in addition, the numbers assigned to the categories can be ranked or ordered in some low-to-high manner

Answer 4

Ordinal (or ranking) scale or level

Question 5

These are variables consisting of categorical scales having a natural ordering of values but with undefined interval distances between the values.

Answer 5

Ordinal (or ranking) scale or level

Question 6

Has all the properties of the ordinal scale, but in addition, the distances or intervals between any 2 numbers on the scale are of known size or magnitude

Answer 6

Interval scale or level

Question 7

must have a common and constant unit of measurement but the unit of measurement is arbitrary in that there is no “true zero” point

Answer 7

Interval scale or level

Question 8

The value zero (0) is assigned to a particular location on the scale simply as a matter of convenience or reference

Answer 8

Interval scale or level

Question 9

Has all the properties of the interval scale, but in addition, it has a “true zero” point which represents none (or the complete absence of the variable being measured)

Answer 9

Ratio scale or level

Question 10

With this scale, we can measure the direction and the size of the difference between two measurements and we can describe the difference in terms of a ratio.

Answer 10

Ratio scale or level

Question 11

Scales of measurement are unimportant because they do not help determine the statistics that are used to evaluate data.

Answer 11

False

Question 12

There are certain statistical procedures that are used with numerical scores from interval or ratio scales and other statistical procedures that are used with non-numerical scores from nominal or ordinal scales

Answer 12

True

Question 13

“classificatory” scale or level

Answer 13

Nominal

Question 14

“ranking” scale or level

Answer 14

Ordinal

Question 15

On the Centigrade scale zero (0) means freezing point. It does not mean a total absence of the variable being measured.

Answer 15

Interval scale or level

Question 16

Measurements on this scale allow us to determine whether two individuals are different, but they do not identify either the direction or the size of the difference

Answer 16

Nominal (classificatory) scale or level

Question 17

All qualitative variables have nominal scales.

Answer 17

True
