Exam 5: Measurement: Research Using Numbers

The established measures technique is a measure of validity.

The word number refers to figures that are labels and cannot be computed.

NOIR in research stands for Nominal, Ordinal, Interval, Ratio.

"Freshman, sophomore, junior, senior" is an example of what level of measurement?

"Press, radio, television" is an example of what level of measurement?

Discuss whether measurement scales can or cannot successfully capture such concepts as intelligence, patriotism, love, or friendship. Support your reasoning with examples wherever possible.

"Numeral" refers to figures that are a basis of measurement and can be computed.

If your results are reliable, it means they must be accurate or true.

If a measure has "face validity," it means the questions appear to measure what they're supposed to measure.

Likert-format questions use a scale anchored by ______.

Semantic differential-format questions use a scale anchored by "strongly agree" and "strongly disagree."

Proprietary measurement instruments are instruments that ______.

Nominal and ordinal data are considered discrete variables.

Reification means that a concept or abstraction is ______.

Numbers and numerals are different things.

The only numbers researchers can get from nominal variables are counts or percentages.

In test-retest, a test is given to a group of people and then repeated, with the same people, a week or two later.

Interval measures assume an equal distance between points on a scale.

Discuss the advantages and disadvantages of using semantic differential scales as a way of measuring human communication.

Intercoder reliability attempts to show that a measure of communication will produce the same results at two different times if everything else is the same.
