Exam 5: Measurement Concepts

The value of Cronbach's alpha is based on an average of:

Which of the following statement is true of the four scales of measurement?

In the context of scales of measurement, the Celsius measure on a household thermometer scale is an example of a(n) _____ scale.

A food critic rates restaurants according to the quality of food, service, and atmosphere. She assigns 4 stars for excellent, 3 for good, 2 for fair, and 1 star for poor. In the context of scales of measurement, this is an example of a(n) _____ scale.

In the context of components of a measure, the more _____ in a test, the smaller the variability of scores in the test.

In the context of reactivity of measures, a measure is said to be reactive if:

A researcher conducts an experiment to establish a relationship between a chess player's mental stability and his performance in the game. He finds that the two have a Pearson product-moment correlation coefficient value of +1.00. This means the two variables-mental stability and performance-have a _____ relationship.

The reactivity of a measure can be reduced by:

_____ reliability is the extent to which raters agree in their observations.

In the context of Pearson product-moment correlation coefficient, the closer a correlation is to 1.00, the _____ is the relationship between two variables.

The positive and negative signs in the Pearson product-moment correlation coefficient provide information about the:

Toby, a researcher, finds that his score on honesty has a high correlation with his score on integrity, which are both measures of character. In the context of construct validity of measures, this finding is an example of _____ validity.

Split-half reliability is as an indicator of _____.

_____ reliability is the assessment of reliability using responses at only one point in time.

_____ validity is the simplest indicator of construct validity of a measure.

If a measure is reliable, then a researcher must find a:

In the context of scales of measurement, _____ scales have an absolute zero point that indicates absence of the variable being measured.

_____ refers to the consistency or stability of a measure of behavior.

Two researchers observe aggressive behaviors displayed by preschool children. The first researcher records a large number of aggressive acts displayed within a one-hour period. The second researcher also records many aggressive acts during the same period. Since both researchers agree in their observations, it can be inferred that the research has _____ reliability.

In the context of reliability, reliability coefficient shows _____ between two variables.
