Question 1

Which of the following represents a main effect without an interaction?

Accepted Answer

B

Question 2

If an interaction were found in a factorial experiment,then:

Accepted Answer

An interaction in a factorial experiment indicates that the effect of one independent variable changes depending on the level of another independent variable. This means the influence of one variable is not consistent across the levels of the other variable, which is what option D describes.

Question 3

What is the minimum number of conditions required in a multi-factor factorial experiment (hint: multiply the minimum number of factors in a multi-factor experiment by the minimum number of levels for any given variable)?

Accepted Answer

A multi-factor factorial experiment requires at least 2 factors, each with a minimum of 2 levels. Multiplying these (2 factors * 2 levels each) gives 4 conditions as the minimum.

Question 4

In a graph of results,an interaction is shown by:

Accepted Answer

An interaction in a graph of results is indicated by two lines that are not parallel to each other. This suggests that the effect of one variable depends on the level of another variable.

Question 5

In a 2 $\times$ 3 factorial experiment using a between-subjects design,each subject serves in ____ condition(s)out of ____ conditions in the experiment.

Accepted Answer

In a 2x3 factorial experiment, there are 2 levels for the first factor and 3 levels for the second factor, making a total of 2*3 = 6 conditions. In a between-subjects design, each subject participates in only 1 condition, making the correct answer 1 out of 6 conditions.

Question 6

Each of the following is a reason for doing multi-factor experiments instead of single factor ones except:

Accepted Answer

The answer of Each of the following is a reason...

Question 7

The word factorial in experimental designs refers to:

Accepted Answer

Testing all combinations of treatment levels is the definition of factorial in experimental designs.

Question 8

In the table below,the pattern of results indicates: $\begin{array}{cccc} 
& & \text { Independent Variable A } \
&& \text { A1 } & \text { A2 } \
& \text { B1 }  & 5 & 10 \
\text { Independent Variable B } \
& \text { B2 } &10 &15
\end{array}$

Accepted Answer

The pattern in the table shows that as you move from A1 to A2, scores increase by 5 for both levels of B (B1 and B2), indicating a main effect for A. Similarly, for both A1 and A2, moving from B1 to B2 also increases scores by 5, indicating a main effect for B. There's no indication of an interaction because the pattern of increase is consistent across levels of the other variable.

Question 9

In the table below,the pattern of results indicates: $\begin{array}{cccc} 
& & \text { Independent Variable A } \
&  & \text { A1 } & \text { A2 } \
&\text { B1 }  & 15 & 15 \
\text { Independent Variable B }&&\
& \text { B2 } & 7 & 7
\end{array}$

Accepted Answer

The results show that the values change significantly between levels of Independent Variable B (from 15 to 7), but not between levels of Independent Variable A (both A1 and A2 have the same values at each level of B). This indicates a main effect for B, as the outcome is consistently different across the levels of B, regardless of the level of A. There is no interaction because the pattern of results is parallel (the difference between A1 and A2 is consistent across levels of B), and there is no main effect for A because the change across A1 and A2 does not vary.

Question 10

One experiment tried to determine whether men prefer women who are blond or women who are brunette.The hair color of the men also was varied.The experimenter found that both blond and brunette men prefer blond women to brunettes,but the effect was much greater for dark-haired men than for blond men.These results show:

Accepted Answer

The results indicate both a main effect (men's preference for blond women over brunettes) and an interaction (the strength of the preference varies by the hair color of the men).

Question 11

When one independent variable has the same effect at all levels of a second,we say that the two variables:

Accepted Answer

When one independent variable has the same effect at all levels of a second, it means the effects of the variables are simply added together without modifying each other's impact. This is referred to as the variables being additive. Interaction would imply that the effect of one variable depends on the level of the other variable, which is not the case here.

Question 12

In the table below,the pattern of results indicates: $\begin{array}{cccc} 
& & \text { Independent Variable A } \
&& \text { A1 } & \text { A2 } \
& \text { B1 }   & 5 & 6 \
\text { Independent Variable B }&&\
& \text { B2 } & 6 & 17
\end{array}$

Accepted Answer

The answer of In the table below,the pattern of results...

Question 13

If a main effect is found in a factorial experiment,then:

Accepted Answer

A main effect in a factorial experiment indicates that there is a significant difference in the dependent variable across the levels of an independent variable, without considering interactions with other variables.

Question 14

In an experiment dealing with recall of high and low imagery words following elaborative or rote rehearsal,the factors are:

Accepted Answer

Factors refer to the independent variables that are manipulated in an experiment. In this case, "word imagery" (high imagery vs. low imagery words) and "rehearsal type" (elaborative vs. rote rehearsal) are the two variables being manipulated to see their effect on recall, making them the factors of the experiment.

Question 15

In the table below,the pattern of results indicates: $\begin{array}{cccc} 
& & \text { Independent Variable A } \
 && \text { A1 } & \text { A2 } \
& \text { B1 } & 10 & 10 \
\text { Independent Variable B }&&\
& \text { B2 } & 5 & 15
\end{array}$

Accepted Answer

The answer of In the table below,the pattern of results...

Question 16

In the table below,the pattern of results indicates: $\begin{array}{cccc} 
& & \text { Independent Variable A } \
 && \text { A1 } & \text { A2 } \
& \text { B1 } & 10 & 5 \
\text { Independent Variable B }&& \
& \text { B2 } & 10 & 15
\end{array}$

Accepted Answer

The answer of In the table below,the pattern of results...

Question 17

Which statement is true regarding interactions in a 2-factor experiment?

Accepted Answer

Interactions describe how the effect of one factor depends on the level of another factor, and they can occur regardless of whether main effects are present. Main effects represent the individual effects of each factor on the outcome, while interactions show how these effects combine or change in the presence of each other, indicating that interactions and main effects are distinct concepts.

Question 18

In a factorial experiment,the number of factors is the number of ____ variables,and the number of levels is the number of instances of each ____ variable included in the experiment.

Accepted Answer

In a factorial experiment, the number of factors refers to the number of independent variables being studied, and the number of levels refers to the number of instances or variations of each independent variable included in the experiment.

Question 19

In a 5 $\times$ 2 $\times$ 3 factorial experiment (between subjects),there are ____ independent groups.

Accepted Answer

In a factorial experiment, the number of independent groups is determined by multiplying the levels of each factor. Here, we have 5 factors (F1, F1, F1, S1, and F10) with levels 1, 1, 1, 1, and 10 respectively. Multiplying these levels (1*1*1*1*10), we get 10 groups. However, since it's a between-subjects design, each combination of factors constitutes a separate group, leading to a total of 10*3 (for the three separate factorial experiments mentioned) = 30 independent groups.

Question 20

An experiment that employs two different factors,one with six levels and one with two levels,and uses all possible combinations,is called a ____ factorial design.

Accepted Answer

This is a 6x2 factorial design, as it involves two factors with one having six levels and the other having two levels, making all possible combinations 6 times 2.
