Question 1

Which of the following is the best definition of a Likert Scale?

Accepted Answer

The Likert Scale is a psychometric scale commonly used in questionnaires, and it is the sum of responses to multiple questions that are intended to measure the same variable. This allows for a more nuanced understanding of a respondent's attitude or feelings towards the subject matter.

Question 2

Which of the following is the least likely goal of pilot testing a survey scale?

Accepted Answer

Pilot testing a survey scale is typically done to refine the survey instrument before it is administered to a larger sample. The goal of pilot testing is primarily to detect problems with the survey, such as ambiguous or confusing items, and to make necessary revisions. Determining the variables to be measured in the survey is a preliminary step that should be completed before the pilot testing stage. The other options (A, B, and D) are common goals of pilot testing a survey scale.

Question 3

David has developed a scale to examine social media addiction. He is concerned about whether the items in his scale are actually measuring the same thing. David is concerned with the ___________________ of his scale.

Accepted Answer

Internal consistency refers to the degree to which the items in a scale measure the same construct. Therefore, David's concern about whether his items are measuring the same thing is an issue of internal consistency. Option B, external validity, refers to the degree to which the findings of a study can be generalized to other populations or settings. Option C, test-retest reliability, refers to the degree to which the same results are obtained when a measure is administered multiple times. Option D, internal validity, refers to the degree to which a study accurately measures the relationship between two variables without being influenced by other factors. While all of these concepts are important in scale development, the best answer for this scenario is A.

Question 4

David's scale measuring social media addiction has a Cronbach's alpha of 0.86. Edison's scale that also measures social media addiction has a Cronbach's alpha of 0.17. Which of the following is true when comparing the Cronbach's alpha of both scales?

Accepted Answer

Cronbach's alpha is a measure of internal consistency reliability, which describes how well the items within a scale are measuring the same construct. A higher Cronbach's alpha indicates better internal consistency. Therefore, David's scale has better internal consistency than Edison's scale (0.86 > 0.17). Test-retest reliability, on the other hand, refers to the stability of scores over time, and is not directly related to Cronbach's alpha.

Question 5

Which of the following is not an example of instrument reliability?

Accepted Answer

Option B is not an example of instrument reliability but instead refers to the construct validity of a survey. Instrument reliability refers to the consistency of the results obtained from an instrument over time or across different respondents. Option A, C, and D all refer to aspects of instrument reliability.
