In a study examining the effect of humor on interpersonal attractions, McGee and Shevlin (2009) found that a man's sense of humor had significant effect on how he was perceieved by woman. In the study, female college students were given brief descriptions of a po tential romantic partner and then rated the attractiveness of the male on a scale from 1 (low) to 7 (high). The fictitious male was described positively as being single , ambitious, and having good job prospects. In one dition, the description also said that he had a great sense of humor. The results showed that the description was rated significantly higher when "a sense of humor" was included. To further examine this effect, a researcher selected a sample of n = 16colle college males and asked them to read a brief description of a female and then rate the attractiveness of the woman in the description . The description had been used in previous research but was modified by adding a statement describing a good sense of humor…

Dr. Guidry conducts a study examining the relationship between the number of
friends one has and the experience of daily stress and life satisfaction. She randomly
samples 1,500 elderly men and women in Nashville, Tennessee (the state capital),

reviewers is concerned about the external validity of her study, which of the
following is the most important aspect of Dr. Guidry's study to consider?
the number of significant findings

A sample of 60 individuals, all in reasonably good health, was selected; 20 individuals were residents of Florida, 20 were residents of New York, and 20 were residents of North Carolina. Each of the individuals sampled was given a standardized test to measure depression. Higher test scores indicate higher levels of depression. A second part of the study considered the relationship between geographic location and depression for individuals 65 years of age or older who had a chronic health condition such as arthritis, hypertension, and/or heart ailment. A sample of 60 individuals with such conditions was identified. Again, 20 were residents of Florida, 20 were residents of New York, and 20 were residents of North Carolina.

- In a 2013 study, Jonason, Jones, and Lyons studied the differences in personality traits of 263 university students and compared those traits to whether the student was a "morning type" or "evening type". They found a those who were evening type to be more, on average, more narrassistic, psychotic, and manipulative. What is the population of this study?arrow_forwardA new study by Brent Teasdal and Eric Silver (Social Problems, February 2009) argues the neighborhood in which children are raised has more to do with their tendency to commit crimes than parents' efforts to keep their kids on the straight-and-narrow. Using data from the National Longitudinal Study of Adolescent Health, the researchers found that regardless of a teen's race, age, gender, or family structure, those who live in lower socioeconomic areas were more likely to commit crimes than those in affluent areas. And that finding held regardless of the lessons parents taught their kids at home. Based on this description, which of the follow is the dependent variable for that study? O Committing crimes Socioeconomic status of the neighborhood Parenting behaviors Agearrow_forwardA researcher in the field of educational psychology is interested in the effects an open classroom has on intellectual development. In the open classroom things are much less structured than in a traditional classroom and she believes that this might affect problem-solving skills. An elementary school in her district switched to an open classroom format last year, and she is interested to see how this has impacted on the kids problem-solving skills. She obtains a random sample of 49 fourth grade children and administers a conceptual problem-solving test to them. It is known that fourth graders in traditional classes have an average score of 82 on the test. The children in this study score an average of 86 with a standard deviation of 5. Use this information to answer the following five questions. If the critical value for this example was 2.423, what would you conclude about the study? Select one: a. Retain the null hypothesis and claim that open classrooms affect problem-solving…arrow_forward
- A researcher seeks to determine whether college seniors are different from freshmen in their attachment to their parents while away at college. To measure this, the researcher collects information about the percentage in each group who call their parents at least once a day. In a random sample of 153 freshmen, this percentage was 24%. In a random sample of 117 seniors, this percentage was 8%. Use the 5-step model and a 1% significance level to report findings for this study. What are the assumptions for this problem? What is the null hypothesis for this problem? Alternate hypothesis? What type of sampling distribution should you use here? What level of significance? Calculate the test statistic. Compare the test statistic to the critical value (in words or with mathematical symbols). Do you reject or fail to reject the null hypothesis? Write a conclusion about the problem in one (1) sentence.arrow_forwardAccording to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Arkansas had 1,601 complaints of identity theft out of 3,482 consumer complaints ("Consumer fraud and," 2008). Do these data provide enough evidence to show that Arkansas had a higher proportion of identity theft than 23%? Test at the 5% level.arrow_forwardSuppose, when conducting a 2-way ANOVA, you find significant main effects for both of your factors of interest (i.e. gender and educational attainment, categorized as high school graduate or less vs. more than a high school education), but no significant interaction between the 2 factors. Which of the following statements, if any, are reasonable conclusions? Question 22 options: A) Since there is no significant interaction between gender and educational attainment, we can conclude that the outcome does not differ between groups. B) Since there is a significant main effect for gender, then the outcome must be significantly different between males and females. C) Since there is a significant main effect for educational attainment, then the outcome must be significantly different between the 2 educational attainment groups. D) All of the above are reasonable conclusions. E) Answers B and C are reasonable…arrow_forward
