An One-Way analysis of variance was conducted to evaluate the null hypothesis that there is no difference in high school students’ level of satisfaction based on their family’s socioeconomic status. The independent variable, socioeconomic status, included three groups: Low (M = 21.36, SD = 4.75, n = 147), Moderate (M = 24.10, SD = 4.15, n = 153), and High (M = 29.73, SD = 6.85, n = 135). The researcher found, F(2 , ? ) = 4.64, p = .01. What is the df for the denominator?
A meta-analysis (Anderson & Bushman, 2001) reported that the average correlation between time spent playing violent video games (X) and engaging in aggressive behavior (Y) in a set of 21 well-controlled experimental studies was +.19. This correlation was judged to be statistically significant. In your own words, what can you say about the nature and strength of the relationship?
In a research study, 100 college students took a personal finances class and 100 students took a personal health class (as a control condition). Two years later all participants completed a survey about their personal finances. A higher score on the survey indicated greater financial health. The mean financial health of the students who took the finance class was M = 29.7, SD = 7.8, while the mean for the other students was M = 28.8, SD = 9.1). The statistical information was t(198) = .75, p = .23, d =.11. Based on these results, which of the following is the best recommendation?"
These data suggest that the intervention is not worth pursuing any further. Start considering how you might revise the intervention to make it more effective.
Start making all students take a personal finance class. The data clearly indicate that it is helping to improve students' financial health 2 years later.

- A marketing research firm is conducting a study to determine if there is a relationship between an individual's age and the individual's preferred source of news. The research firm asked 1,000 individuals to list their preferred sources for news; newspaper, radio, and television, or the Internet. The accompanying results were obtained. At the 0.01 level of significance, can the marketing research firm conclusion that there is a relationship between the age of the individual and the individual's preferred source for news?

The total time (in minutes) a subject spent on the Trail Making Test (a standard psychological test) was used as a measure of cognitive function. The researchers theorize that the mean time on the Trail Making Test for schizophrenics will be larger than the corresponding mean for normal subjects. The data for independent random samples of 41 schizophrenics and 49 normal individuals yielded the following results: ***PHOTO Does the data provide significant evidence, at the 4.6% level, that the population mean time for patients diagnosed with schizophrenia exceeds the population mean time for normal individuals by more than 20 points?arrow_forward
- A nutrition store in the mall is selling “Memory Booster” which is a concoction of herbs and minerals that is intended to improve memory performance. To test the effectiveness of the herbal mix, a researcher obtains a sample of n = 16 people and has each person take the suggested dosage every day for 4 weeks. At the end of the four week period, each individual takes a standardized memory test. The scores from the sample produced a mean ??� = 24 with a sample variance s2 = 64. In the general population, the standardized test is known to have a mean μ =20. Do the sample data support the conclusion that the Memory Booster has a significant effect?

The memory recall abilities of each student were assessed both before and after they underwent training in the memory technique. The observed average increase in memory recall scores following the training was 5 points. The sample variance of the differences within the entire sample was denoted as 8. Does this research question aim to ascertain whether there is a statistically significant elevation in memory recall scores after the implementation of the memory improvement training? To address this question, a one-tailed test with a significance level of (alpha = 0.01) is employed.arrow_forwardA recent article reported “A one-way analysis of variance found that GRE scores varied according to the type of test preparation students engaged in prior to taking the examination, F (4, 187) = 14.08, p < .01.”arrow_forward
