1. please provide a simple, common-sense explanation for the pattern of results they describe in this post. Your job is to explain why these results happen in this way.
“1: Identify the two IVs and the DV.
The two IVs are Amnesic and Non-Amnesic.
The DV is Memory. The DV has two categories: Explicit and Implicit.
2: Identify whether there are any main effects – if there are, describe them.
The main effects are the following.
People with and without amnesia perform the same in the implicit memory test.
Both groups score 20 for the implicit memory test.
In the explicit memory test, however, the scores for both groups are lower than in the implicit memory test.
For the amnesic group it is significantly lower with a score of 5, compared to the non-amnesic group with a score of 15.
3: Identify whether there is an interaction – if so, describe the interaction in words.
The difference in the implicit memory test between the amnesic and non-amnesic group is zero.
The difference in the explicit memory test between the amnesic and non-amnesic group is 10.
So, there is a difference in the differences.
When drawing a bar graph the lines would cross, which means we have an interaction.
Specifically the implicit memory test would have a straight horizontal line and the explicit memory test would have a line starting at 5 and going up to 15.
If we would continue the explicit memory line it would cross the implicit memory line.”

“1. The two independent variables are the amount of sleep before the exam (6 hours / 8 hours) and the caffeine intake (yes/no). The dependent variable is the performance on the exam.
2. The average score of the 6-hour sleep condition is 75, and the 8-hour sleep condition is 82.5. Since there is a noticeable difference between these two conditions, we can say that the amount of sleep has a main effect.
Similarly, the average score of the no caffeine condition is 75, and the caffeine condition is 82.5, so we can say that the intake of caffeine also has a main effect.
3. We can observe that although the performance of “no caffeine” group increased as the amount of sleep increased, the performance of the “caffeine” group actually decreased as the amount of sleep increased. Therefore we can say that there is a crossover interaction.”
