- A researcher is studying whether average GPA is dependent on whether the students are in a 2-year college, public university, or private university. The researcher should use a 1-way ANOVA for this study. True or falseA researcher wants to test a new memory performance supplement that has shown some promise in primate studies where subjects were given the supplement followed by the task of identifying pictures of other animals three days later. The dependent variable was measured by the number of pictures correctly identified. The researchers noticed that while there was a positive correlation between the group given the supplement and number of correctly identified pictures as compared to the control group, they also notice that there seemed to be some variation between the males and females of the primates. Additionally, two different amounts of the drug have been proposed for consideration. Therefore, in the current study, the researchers want to divide the subject primates (N=60) by gender (male: n=30; female: n=30), and give them a 10 mg dose in one treatment condition, and a 25 mg dose in the other treatment condition. To do this, they are dividing each group of males and females in half, and…A researcher gathered a sample of participants who volunteered for a studying of phobias. She measured anxiety level of participants as they viewed photos of spiders and again when they viewed puppies. Which statistical test is appropriate for this study and why?
- Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?When you get a surprisingly low price on a product do you assume that you got a really good deal or that you bought a low-quality product? Research indicates that you are more likely to associate low price and low quality if someone else makes the purchase rather than yourself. In a similar study, 16 participants were asked to rate the quality of low-priced items under two scenarios: purchased by a friend or purchased yourself. The results produced a mean difference of 2.6 and a SS = 135, with self-purchases rated higher. Is there evidence that the judged quality of objects significantly increase for self-purchases than for purchases made by others? Please use a one-tailed test with level of significance of 5%.A study is testing the effectiveness of a new allergy medication. Sixty people who reported they have allergies volunteered to be part of the study and were randomly assigned to one of two groups, as shown in the design web. 30 Receive Medication Randomly Assigned Compare Level of Allerg Symptoms after Severa Weeks 60 Subjects 30 Receive Placebo Which of the following accurately describes the benefit of comparison in the experiment shown in the design web? The level of allergic symptoms in both groups can be compared to see if the new medication had a significant effect. The overall level of allergic symptoms can be used to determine if the new allergy medication had a significant effect. The level of allergic symptoms in the group who received the medication can be used to determine if the medication had a significant effect. The level of allergic symptoms in both groups cannot be compared to determine if the medication had a significant effect because one group only received a…
- If no main effects emerge in a two-factor ANOVA, there must also be no significant interaction between the two factors. Group of answer choices True FalseThe personality characteristics of business leaders (e.g., CEOS) are related to the operations of the businesses that they lead (Oreg & Berson, 2018). Traits like openness to experience are related to positive financial outcomes and other traits are related to negative financial outcomes for their businesses. Suppose that a board of directors is interested in evaluating the personality of their leadership. Among a sample of n = 16 managers, the sample mean of the openness to experiences dimension of personality was M = 4.50. Assuming that u = 4.24 and o = 1.05 (Cobb-Clark & Schurer, 2012), use a two-tailed hypothesis test with a = .05 to test the hypothesis that this company's business leaders' openness to experience is different from the population. Standard Normal Distribution Mean - 0.0 Standard Deviation 1.0 .7198 .1401 .1401 -3.0 -2.0 -1.0 0.0 1.0 2.0 3.0 -1.08 1.08 Step 1. Ho: ; H;: a = .05. Step 2. The critical region consists of Step 3. For these data the standard error is and…If the results of a two-factor ANOVA show no main effect for factor A but show a significant interaction, then the results indicate that factor A has no effect on the subjects' scores. True or False
- An immunologist is testing the hypothesis that the current flu vaccine is less than 71% effective against the flu virus. The immunologist is using a 10% significance level and thesehypotheses: H0: p=0.71 and Ha: p<0.71. Explain what the 10% significance level means in context.Question The result of a One-Way ANOVA for total stress symptoms among four groups of teachers (pre-k, elementary, middle, high school) was F(3, 117) = 3.82, p < .05. The corresponding effect size was η2 = .265. What can be concluded about these results? Answer choices: For total stress symptoms, there was not significant difference among groups. For total stress symptoms, there was a significant difference among groups. The effect size was small. For total stress symptoms, there was a significant difference among groups. The effect size was medium. For total stress symptoms, there was a significant difference among groups. The effect size was very large.A researcher is studying psychological factors in artistic achievement among teenage girls. One variable he is particularly interested in is perseverance.
