15Imagine you are a researcher interested in the effects of marijuana on memory. The study involves two groups, to which people are assigned by chance: Group A takes a pill that contains the active ingredient in cannabis, THC, while Group B are given a harmless placebo pill. Neither the people conducting the study nor the participants know who is getting the drug and who is not. After taking the pill, participants are given a long list of word pairs to learn. One hour later, they're given a memory test for the word pairs.

24A researcher wondered if people have greater need of stuffed animals when they are feeling lonely. They assigned participants randomly to conditions where they either wrote about a recent time when they felt rejected by other people or about a recent time that they went grocery shopping. They then had participants take a product evaluation survey, where they rated the desirability of several products on a 9 point scale, with 1 as “not at all desirable”, 5 as “neutral”, and 9 as “highly desirable.” One of these products was a teddy bear.
When people wrote about a time they were socially rejected, they rated the teddy bear as highly desirable (Mean = 8.40, Standard Deviation = .60) whereas when people wrote about a time they went grocery shopping, their ratings of the teddy bear were more neutral (Mean = 4.79, Standard Deviation = .72). These are [blank_start]descriptive[blank_end] statistics. The mean is a measure of [blank_start]central tendency[blank_end] and the standard deviation is a measure of [blank_start]variability[blank_end].
This difference was statistically significant, t(120) = 11.20, p = .02. The t-test is an example of [blank_start]inferential[blank_end] statistics.- Ainferential
- Bdescriptive
- Cvariability
- Dcentral tendency
- Edescriptive
- Finferential
- Gcentral tendency
- Hvariability
25A researcher wondered if people have greater need of stuffed animals when they are feeling lonely. They assigned participants randomly to conditions where they either wrote about a recent time when they felt rejected by other people or about a recent time that they went grocery shopping. They then had participants take a product evaluation survey, where they rated the desirability of several products on a 9 point scale, with 1 as “not at all desirable”, 5 as “neutral”, and 9 as “highly desirable.” One of these products was a teddy bear.
The results in the above study were statistically significant. What does this mean?- AThe observed effect (higher ratings of the teddy bear when socially rejected) is practically important and meaningful.
- BThe observed effect (higher ratings of the teddy bear when socially rejected) is very likely to have occurred by chance.
- CThe observed effect (higher ratings of the teddy bear when socially rejected) is not very likely to have occurred by chance.
- DIt proves the observed effect (higher ratings of the teddy bear when socially rejected) is real.

27Dr. Buttercup wants to do a survey about how people's personality types relate to their favorite colors and hobbies. She wants to use horoscopes as a way of measuring personality because a person's horoscope never changes. (Horoscopes are based on birthdays.)
Which statement is true?- AHoroscopes are unreliable
- BBecause horoscopes are highly reliable, they would be an appropriate and valid way to measure personality.
- CAlthough horoscopes may be reliable, they are not valid since research suggests horoscopes have no relation to personality.
- DHoroscopes cannot be measured accurately and should be avoided.
