Question

Imagine that I was interested in the effect of benevolent intentions on pleasure. Participants received one of two types of goodies: a tootsie roll with a note that read, “I picked this goodie just for you. I hope you like it!” or a note that read, “I was told to pick this goodie. So, whatever.” After the participants completed a puzzle and ate the candy they were asked how delicious they thought the good was on a scale that ranged from 1 (not at all delicious) to 6 (extremely delicious). The data are below.

Benevolent condition, M = 4.55, SD = 2.10          Apathetic condition, M = 2. 30 SD = 1.25

Describe the mean differences in plain language.

Describe the variability in both conditions.

Decide which statistical test you should use.

Imagine the following data: t(38) = 6.38, p < .001. What would you conclude about the effect of benevolent intention on pleasure?

Which of the above is an inferential statistic?

Write an APA style sentence describing the descriptive and inferential statistics.

Application Activity 3

Imagine a researcher conducted a study using survey/correlation methods. She asked people complete the Happiness Scale and she asked how often they go on vacation. Then she correlated happiness and vacation frequency to see if there was a relationship. Finally, she divided people into four groups based on their income and examined the relationships separately.

Poor folks           Moderate income folks                Rich folks           Filthy Rich folks

r(34) = .62                          r(36) = .59                          r(24) = .44          r(20) = .30

1)Describe the relationship between vacation frequency and happiness for rich folks.

2)In which group is the relationship between vacation frequency and happiness strongest?

3)What is the best interpretation of the data for moderate income folks?

4)Which of the following would support your above conclusion?

r(36) = .59, p = .06

r(36) = .59, p = .08

r(36) = .59, p = .05

r(36) = .59, p = .16

5)Below are the actual data for moderate income folks. Given the data write an APA style sentence.

r = .56

df = 32

p < .001

Answer 1

1. In this study, the mean differences reflect that participants who received a benevolent note with their candy rated the candy as more delicious compared to those who received an apathetic note.
2. There was greater variability of scores in the benevolent condition in comparison to the apathetic condition. This means that the group scores were more spread out around the average in the benevolent condition.
3. The t-test should be used in this study.
4. From these values, we can conclude that benevolent intention indeed has an effect on pleasure. This is because the p-value is less than the 0.01 level of significance.
