Idiographic research

Question 3

Which of the following characteristics is present in a typical case study?

Accepted Answer

Several different treatments are often applied simultaneously

Question 4

Idiographic research, as represented by the case study method, has the potential to reveal:

Accepted Answer

Nuances and subtleties of individual behavior

Question 5

The level of significance, or alpha, in psychological research is generally set at:

Accepted Answer

.05

Question 6

In the multiple-baseline design across individuals, the treatment is administered:

Accepted Answer

Successively to one individual at a time

Question 7

The results of an omnibus F-test for a complex design experiment allow the researcher to:

Accepted Answer

Know whether the interaction and main effects are statistically significant

Question 8

If a researcher were to use a .01 level of significance rather than .05, the probability of a Type II error would:

Accepted Answer

Increase

Question 9

The application of single-case experimental designs to socially relevant problems has its origin in:

Accepted Answer

Behaviorism and the experimental analysis of behavior

Question 10

In order to conclude whether the results of an inferential test support the research hypothesis, a researcher must:

Accepted Answer

Examine the descriptive (summary) statistics

Question 11

Which is not an acceptable approach for addressing the problem of excessive baseline variability in single-case designs?

Accepted Answer

Dropping results for subjects whose baselines show excessive variability

Question 12

An intensive descriptive study was done on someone with an unusual brain injury. Which method was likely used?

Accepted Answer

Case study method

Question 13

The F-test provides a statistic that represents the ratio of between-group variation in the data to ____________

Accepted Answer

Within-group variation

Question 14

The fundamental characteristic of case studies is:

Accepted Answer

They lack a high degree of scientific control

Question 15

The main difference between analysis of variance for repeated measures and independent groups design is estimation of:

Accepted Answer

Error variation

Question 16

The null hypothesis is the assumption that the independent variable:

Accepted Answer

Had no effect

Question 17

Two measures of effect size for an independent groups design with more than two means are:

Accepted Answer

Eta-squared and Cohen&#x27;s f.

Question 18

Results that are "statistically significant" may not be of interest to the scientific community because:

Accepted Answer

Any of the above

Question 19

The probability we use to define a statistically significant outcome is called:

Accepted Answer

Alpha

Question 20

Which of the following is an advantage of the case study method?

Accepted Answer

They provide ideas and hypotheses about behavior

Question 21

Problems of observer bias can arise in the context of a case study because:

Accepted Answer

The researcher is often both observer and participant

Question 22

The relationship of the case study method to other research methods of investigation can best be described as:

Accepted Answer

Interrelated with and complementary to other methods

Question 23

Extraneous variables are very hard to control in the case study method. This makes it difficult to use case studies to:

Accepted Answer

Draw cause-and-effect conclusions about behavior

Question 24

In general, a repeated measures design is likely to be __________ than a random groups design

Accepted Answer

More sensitive

Question 25

The initial overall analysis of an xperiment based on the analysis of variance is called:

Accepted Answer

An omnibus F-test
