A post-hoc test is warranted when: Question 32 options: the F is significant and there are more than two groups we reject the null hypothesis when performing an independent-groups t test. we have an apriori prediction about which group means will differ we fail to reject the null hypothesis in an ANOVA

Given statement is : A post-hoc test is warranted.A post-hoc test is used to find the specific mean differences in case the result of anova is significant when the test includes more than 2 groups. Therefore, the correct option is The F is significant and there are more than two groups First Option is correct choice.

Answered: A post-hoc test is warranted when:…

Ch 10 Research suggests that playing action video games might improve hand-eye coordination (Li, Chen & Chen, 2016). Researchers compared 16 participants who played video games frequently to 16 participants who rarely or never played video games on participant’s errors using a joystick to play a game. Use α = .01 2tail to evaluate the statistic. The results of the SPSS statistical analyses are below: **attached as images** a. State the hypotheses b. Show how the t was calculated using the values from the SPSS printout. c. What is Cohen’s d? d. Show how the 95% confidence interval was calculated. e. State the conclusion in APA format

A random sample of 200 middle school students was collected and the students were asked the question, "If you could have only one type of pet, what would it be?” The responses, separated by grade, are shown in the table. A teacher wants to perform a chi-square test of independence/association on the data. Are the conditions for such a test met? A. Yes, the sample size of 200 is large B. Yes, all the expected cell counts are 5 or higher. C. Yes, all the observed cell counts are 5 or higher. D. No, not all the observed counts are above 5. E. No, some of the expected cell counts are below 5.
Suppose that a medical clinic wants to test whether there is a relationship between sex and age class in the number of deaths caused by cancer. The table shows the observed frequencies (counts) of a simple random sample of 117 deaths related to cancer. Younger than 45 45 and older Total Male 8 60 68 Female 4 45 49 Total 12 105 117 Does this sample meet the requirements for conducting a chi-square test for independence? The sample does not meet the requirements because the expected frequency in at least one cell is less than 10. The sample does not meet the requirements because the expected frequency in at least one cell is less than 5. The sample does not meet the requirements because the observations are not independent. The sample meets the requirements because the observed frequency in each cell is at least 5. The sample meets the requirements because the expected frequency in each cell is at least 5.
