Robert notices that several respondents did not answer the question of whether they took out loans to fund their education.However,later in his survey,Robert finds that respondents told him about the source(s) and the amount(s) of their college loans.In handling the missing data on the question of whether or not they had a college loan,Robert's best approach is to:

Question 11

Using Likert-type scale items,Professor Wong developed an index to assess job morale.Wong administered the index to 2,000 workers and found that 1 to 4 responses were missing on each of the items.Wong could:

Accepted Answer

A)  Exclude the cases that contained the missing data from the analysis.
B)  Assign the middle value to cases with missing data.
C)  Analyze the cases that had missing data to interpret their meaning.
D)  Assign values at random.
E)  All of these choices.

Question 12

A(n) summarizes the intersection of two or more variables.

Accepted Answer

A)  guttman scale
B)  likert scale
C)  semantic differential scale
D)  index
E)  typology

Question 13

Professor Swanson developed an index of marital happiness.Several items in Swanson's questionnaire were not a part of the index (i.e. ,"How many serious quarrels or arguments have you had with your spouse in the past year?") Swanson compared the index scores of marital happiness with these questions.Swanson was doing:

Accepted Answer

A)  index validation.
B)  item analysis.
C)  external validation.
D)  index validation and item analysis.
E)  index validation and external validation.

Question 14

Indexes must be made up of:

Accepted Answer

A)  nominal variables.
B)  ordinal variables.
C)  interval variables.
D)  ratio variables.
E)  any type or combination of variables.

Question 15

Jeremy includes items that measure sexism in his index of gender roles.He does this because he believes the two variables are empirically related.As a methodology student,you should tell Jeremy that:

Accepted Answer

A)  it's a great idea,and he should do it.
B)  if he includes both the variables in his index he is violating concerns about the general or specific dimensions of an index.
C)  if he includes both the variables in his index he needs to examine the bivariate correlations between them to be sure they are empirically correlated.
D)  if he includes both the variables in his index he is violating the criteria specifying the need for unidimensionality in index construction.
E)  great idea as long as the bivariate correlations among the variables exceed 0.9

Question 16

Compare and contrast the various types of scales.How do they differ from an index?

Accepted Answer

A typical answer should include the following items:
Likert scale,Thurstone scale,Bogardus Social Distance scale,and Semantic differential scales.Student responses should focus on how they are all composite measures designed to elicit simplified and consistent responses on a variety of indicators.The second part of the question should include that scales and indexes are both composite measures intended to simplify explanation,but that one is a way to standardize indicators,while the other simplifies the actual variables.

Question 17

According to Babbie,as a general guideline the coefficient of reproducibility for a Guttman scale should be:

Accepted Answer

A)  100 percent
B)  90 or 95 percent
C)  80 or 85 percent
D)  70 percent
E)  It doesn't matter

Question 18

Among the reasons for the frequent use of composite measures is(are) that:

Accepted Answer

A)  the researcher is seldom able to develop in advance single indicators of complex concepts.
B)  a single data item might not have enough categories to provide a range of variation.
C)  composite measures give a more comprehensive and accurate indication of a given variable.
D)  they are efficient data reduction devices.
E)  all of these choices. E

Question 19

Which of the following statements is FALSE while determining the relative strengths of the items of bivariate relationships?

Accepted Answer

A)  Be wary of including items in a composite measure that are not related to one another empirically.
B)  One should probably drop any item that is not related to several other items in the composite measure.
C)  variable very strong relationship between two items presents a problem.
D)  One must check the bivariate correlations between all items that one plans to include in the composite measure.
E)  You should strive for perfectly correlated (1.0) indicators within a composite measure.

Question 20

For an index or scale to be considered unidimensional,its component items should be indicators of only one dimension of a concept.

Accepted Answer

A) True 
 B)False
