A bivariate relationship is between two or more variables.
False
A nominal measure can have only two categories.
False
A split-half reliability test taps the idea of the general stability of the instrument over time.
False
An index is constructed by assigning scores to patterns of responses.
False
Both scales and indexes are interval measures.
False
Conceptualization is the development of research procedures that will result in empirical observations representing those concepts in the real world.
False
Even if a pre-existing measure of a construct of interest exists, it is a better idea to create your own so you understand it better.
False
If a measure is reliable, it must also be valid.
False
If two items are perfectly correlated, both should be included in an index.
False
If unsure as a researcher how specific a measurement needs to be, it is best to be more general to simplify data collection.
False
It is impossible to have several indicators of only once concept.
False
Item analysis allows you to examine the extent to which the composite index is related to other items in the questionnaire that are not part of the index.
False
Number of arrests would be an example of an interval measurement.
False
Numbers assigned to ranks on an ordinal scale can legitimately be added, multiplied, subtracted, and divided.
False
One only need a nominal definition of a concept before beginning the process of data collection.
False
Precise measurement is more important accurate measurement.
False
Precision and accuracy are synonyms.
False
The only thing one can do when building an index with missing data is drop cases where data is missing.
False
Calculating a correlation will allow you to determine how closely related indicators are.
True
Changing definitions almost inevitably results in different descriptive conclusions.
True
Definitions are more problematic for descriptive research than for explanatory research.
True
For an index or scale to be considered unidimensional, its component items should be indicators of only one dimension of a concept.
True
Perfectly correlated indicators are not useful in an index.
True
Predictive validity is often used as another term for criterion-related validity.
True
The split-half technique for assessing reliability is closely linked to concept of the interchangeability of indicators.
True
The test-retest method assumes that the phenomena under study does not change.
True
Unless there are compelling reasons for differential weighting, items should be equally weighted.
True
Validity refers to the extent to which an empirical measure adequately reflects the real meaning of the concept under consideration.
True
