Question 1

(Scenario I) In Scenario I, the between-subjects variable was _____, and the within-subjects variable was _____.

Accepted Answer

In a between-subjects design, different groups are exposed to different conditions, whereas in a within-subjects design, the same group is exposed to all conditions. The correct answer indicates that the modality at test varied between different groups of subjects (between-subjects variable), and the modality at study varied for the same subjects across conditions (within-subjects variable).

Question 2

Dr. Domnica conducted a mixed design ANOVA in reference to her study examining the effects of marijuana use and alcohol consumption on several prenatal domains of development. Dr. Domnica had the following outcome: F(1, 106) = 11.2, p = .04, eta² = .13. Which number represents the within-subjects degrees of freedom?

Accepted Answer

The within-subjects degrees of freedom is represented by the first number in the parentheses following the F statistic, which in this case is 1 (F(1, 106)).

Question 3

(Scenario II) The purpose of removing the intervention in Scenario II was to:

Accepted Answer

Establishing causality often involves manipulating variables to observe the effect of removing or altering an intervention, which can help determine if the intervention directly causes changes in the outcome.

Question 4

(Scenario II) The study described in Scenario II uses an _____ design.

Accepted Answer

The answer of (Scenario II) The study described in Scenario...

Question 5

(Scenario III) The researcher who recorded the distance that each rat ran did not know whether the rat had received stress. This resulted in a(n) _____ and decreased _____.

Accepted Answer

This is a single-blind procedure because the researcher did not know which condition the rats were in, which decreases experimenter expectancy effects because the researcher's expectations cannot influence the outcome.

Question 6

(Scenario III) Which type of statistic was used to determine if there was an effect of stress on running at weeks 2, 3 and 4?

Accepted Answer

A mixed design ANOVA is used when there are both within-subjects (repeated measures over weeks 2, 3, and 4) and between-subjects variables (e.g., stress vs. no stress), which seems to be the case in this scenario.

Question 7

Dr. Marks is using a within-subjects design in which there is one participant whom he is assessing change on the variables of interest. Dr. Marks is conducting:

Accepted Answer

A single-subject design focuses on observing and measuring the effect of an intervention or treatment on one individual over time, which aligns with Dr. Marks' approach of assessing change on variables of interest in one participant.

Question 8

Dr. Reid conducted a mixed design ANOVA in reference to her study examining the effects of marijuana use and alcohol consumption on several prenatal domains of development. Dr. Reid had the following outcome: F(1, 202) = 8.2, p = .03, eta² = .17. Which number represents the significance value?

Accepted Answer

The significance value in statistical results is represented by "p". In this case, the significance value is .03, indicating the probability that the observed results occurred by chance.

Accepted Answer

The answer of Dr. Domnica conducted a mixed design ANOVA...

Question 15

_____ is a quantitative statistical analysis that compares and combines the results of individual but similar studies.

Accepted Answer

A meta-analysis is a statistical technique that combines the results of multiple scientific studies on the same subject to integrate findings and draw conclusions from a larger sample size than any individual study.

Question 16

(Scenario I) In Scenario I the nature of the stimuli (haptic and visual) during the study and test phase made:

Accepted Answer

The nature of the stimuli (haptic and visual) could make it challenging to blind the participants or the researchers to the conditions, potentially introducing experimenter-expectancy effects, thus making all of the options correct.

Question 17

(Scenario I) The design described in Scenario I is a:

Accepted Answer

The answer of (Scenario I) The design described in Scenario...

Question 18

Dr. Domnica conducted a mixed design ANOVA in reference to her study examining the effects of marijuana use and alcohol consumption on several prenatal domains of development. Dr. Domnica had the following outcome: F(1, 106) = 11.2, p = .04, eta² = .13. Which number represents the F score?

Accepted Answer

The F score in an ANOVA output is represented by the value that comes immediately after the F statistic notation. In this case, it is 11.2.

Question 19

The refusal to maintain a healthy body weight, a fear of gaining weight, and altered cognitions and perceptions of one's own body weight describes:

Accepted Answer

Anorexia nervosa is characterized by a refusal to maintain a healthy body weight, an intense fear of gaining weight, and a distorted body image, where individuals see themselves as overweight even if they are underweight.

Question 20

(Scenario III) In Scenario III, the between-subjects variable was _____, and the within-subjects variable was _____.

Accepted Answer

In a between-subjects design, different groups are exposed to different conditions, while in a within-subjects design, the same group is exposed to all conditions. The scenario suggests stress varies between different groups (between-subjects variable) and time is measured within the same subjects (within-subjects variable).
