Question
I think my brain is seriously going on strike now that we have reached the end. I have been stuck on this for quite awhile. can someone give me guidance.
Interpret a graph (17 points) Yo u predict that people perform faster on a task the second time they do it than the first time they do it (Hypothesis 1). You also think that people for whom an accuracy motive is not tivated are slower than people for whom an accuracy motive is activated (Hypothesis 2) ever, you think that "accuracy participa nts" are slower (than no accuracy motive participants) during the initial measurement, but faster (than no accuracy motive participants) during the second measurement (Hypothesis 3). Following is a graph of the results of your experiment. (Don't be fooled by the DV here: higher reaction times indicate slower responding - I Accuracy -motive No accurad Motive motive Time 1 Time 2 Time 1. 2. 3. What are the IVs and their levels? (3 point) What is the DV? (2 point) What kind of test would you conduct to analyze your data (use the correct notation)? (2 points) 4. Based on the graph, which of the following possible effects are present? YES NO YES NO YES NO Main effect of Time Main effect of Motive Interaction of Time and Motive Simple effect of Time at Accuracy motive Simple effect of Time at No accuracy motive Simple effect of Motive at Time 1 Simple effect of Motive at Time 2 YES NO YES YES NO NO YES NO 5. Based on this graph, does it appear that the hypotheses are supported? Why or why not? Hypothesis 2Explanation / Answer
1.
The IVs are:
Time - levels are Time 1 and Time 2
Motive - levels are Accuracy motive and no accuracy motive
2.
The DV is:
Reaction time
3.
To test the hypotheses,
we would use a two way ANOVA test with interaction
This is because there are 2 IV
And both of them are categorical with 2 levels
We want to compare the effect of both IVs on the DV in hypothesis 1 and hypothesis 2
The 3rd hypothesis compares the interaction effect between the 2 IVs on the dependent variable.
4.
Main effect of time:
Time 1 - DV = 5 + 4 =9
Time 2 - DV = 3 + 4 = 7
So, yes this effect is possible.
Main effect of motive:
Accuracy motive - DV = 5 + 3 = 8
No accuracy motive - DV = 4 + 4 = 8
So, no this effect may be not possible.
Interaction of time and motive:
Time 1 Accuracy - DV = 5
Time 2 Accuarcy - DV = 3
So, yes this effect may be possible.
Simple effect of time at accuarcy motive:
time 1 at accuarcy motive - DV = 5
time 2 at accuarcy motive - DV = 3
So, yes this effect may be possible.
Simple effect of time at no accuarcy motive:
time 1 at no accuarcy motive - DV = 4
time 2 at no accuarcy motive - DV = 4
So, no this effect may not be possible..
simple effect of motive at time 1:
accuarcy motive at time 1 - DV = 5
no accuracy motive at time 1 - DV = 4
So, yes this effect may be possible.
simple effect of motive at time 2:
accuarcy motive at time 2 - DV = 3
no accuracy motive at time 2 - DV = 4
So, yes this effect may be possible.
