Researchers studied the impact of social support on people's' ability to cope with stress. Data were collected in 3 conditions: (a) Low Social Support (Control Group): Participants have limited access to social support. (b) Moderate Social Support: Participants have moderate access to social support. (c) High Social Support: Participants have a high level of social support available. Participants were randomly assigned to one of the three social support conditions. They are exposed to a standardized stressor, and their level of stress was assessed using a self-report measure. Here are the data: Social support Level of stress low 9, 11, 7, 9, 9,9 moderate high 12, 13, 12, 10, 11, 11 8, 7, 8, 8, 6 And here is a summary of the preliminary analyses: social support x² T n SS low 494 54 6 8.0 moderate 799 69 6 5.5 high 277 37 5 3.2 X2 1570, G = 160, N = 17 1.

A sports psychologist studied the effect of a motivational program on number of injuries in one year among players of three different sports (baseball, football, and basketball). Players were randomly assigned to one of two conditions: either participate in a motivational program or none (control). Data was collected on the number of injuries sustained by each athlete that season. Question: If p = .024 for the main effect of sports, what should the researcher conclude?

You want to compare males and females in their use of coping strategies when engaged in conflict in relationships. You send surveys to couples obtained from marriage license application at the county clerk's office. You identify several distinct coping strategies on the survey and have the respondents rate their use of each strategy on a 7-point scale. You then compare scores that come from the two members of each relationship. If testing hypotheses about the effects of gender on use of coping strategies, it would be most appropriate to calculate a ... 1) independent-samples t 2) one sample t 3) paired samples t 4) z test

One-Factor Between-subjects and Within-subjects ANOVA: Jessica Black and Jennifer Barnes (2015) investigated whether watchinghigh-quality television dramas improve one’s theory of mind (essentially, our ability to understand other people’s mental states, such as beliefs, desires, intentions, emotions, etc.). They randomly assigned participants to watch an award-winning TV drama (The Good Wife), an award-winning documentary (Through the Wormhole), or no TV at all. Then, they were asked to look at a series of 36 photos of people’s eyes and decide if each person was jealous, panicked, arrogant, or hateful. Scores ranged from 0 (guessed no emotions correctly) to 36 (guessed every emotion correctly). How many factors are in this study?:How many levels are there for each factor(s)?:What is the dependent variable?:

I collected data on levels of anxiety after receiving three types of therapies (CBT, psycho education, and psycho analysis). Below are the anxiety scores for 9 patients. Is there a difference in anxiety based on treatment type ?  CBT: 3, 2, 0 Psycho Education: 8, 8, 9 Psycho Analysis: 10, 12, 12   (Look at the table)

Borderline personality disorder (BPD) is a psychological illness marked by an ongoing pattern of varying moods, self-image, and behavior. A psychologist wants to evaluate the effectiveness of dialectical behavior therapy (DBT) on BPD in a two month study. The psychologist randomly selected 500 people who have BPD to participate in a study. The 500 participants were divided into two groups based on gender. The first group, contained 344 females, they were given medication along with DBT therapy. The second group were comprised of 156 males, they received medication alone. At the end of the two month study, the psychologist administered a standard test to evaluate the symptoms of BPD. It was found that the group that received the DBT therapy along with the medication had about the same level of improvement in symptoms as the group that received the medication alone. The psychologist concluded that there is no evidence that DBT therapy is effective at improving the symptoms of Borderline…

The 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.

Hospital administrators at a local hospital are interested in quality of care.  As such, they ask a random sample of patients that have used the hospital's health care services to fill out a questionnaire.  The questionnaire has questions about the patient's worry (negative, positive), the hospital staff's communication skills (low, medium, high), and satisfaction with medical care.  The administrators are interested in how patient's worry and their assessment of the hospital staff's communication impact their satisfaction with medical care.  The survey data are below.  What can the administrators conclude with an α of 0.01?   Communication Worry low med high negative 76868 54545 67495 positive 86677 78687 78666   A) Input the appropriate value(s) to make a decision about H0.Worry: p-value =  Communication: p-value = Interaction: p-value =  B) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).Worry:  η2 =  Communication:  η2 =…

A doctor wanted to study the effect of four different treatments on mental health. A group of 100 adults experiencing depression volunteered for the study. The doctor randomly assigned one-fourth of them to each of four groups. Group 1 followed a specific exercise plan, group 2 followed a specific diet plan, group 3 followed an exercise and diet plan, and group 4 did not follow any plan. After 4 weeks, the doctor contacted each participant and asked them if they felt any better. The results are displayed in the table.    The doctor would like to know if these data provide convincing evidence that the distribution of responses differs across the treatment groups in the population of all patients like these. The random condition is met. The 10% condition is not needed because random sampling did not take place. This table of expected counts shows that all expected counts are at least 5.   What is the value of the chi-square test statistic? χ‑2 = 5.03 χ‑2 = 6.26 χ‑2 = 25.33 χ‑2 = 39.22
