Provide a rationale for your answer. The mental health t ratio of t = -3.15 ratio indicates the largest difference between the males and females post MI in this study. This t ratio is significant since it is causing the p value to be significantly low, less than the alpha 0.05 set for the study. 5. Consider t = −2.50 and t = −2.54.
The mean baseline and posttest depression score of the control group were exactly the same. These scores increase the validity of the research results because the fact that it did not change shows that the lack of any sort of intervention is not effective in decreasing depression. To have this finding of the control group compared with the decreased depression in those who had interventions with the empowerment program (the experimental group) manifests the effectiveness the empowerment program can have on ESRD patients. 5. Which group’s test scores had the least amount of variability or dispersion?
Both values are normal because they are between the normal ranges: for males between 42-52% and for females between 42-47%. 2. Describe the difference between the hematocrits for the male and female living in Boston. Why does this difference between the sexes exist? The difference in the hematocrits level is perfectly normal because males usually have higher hematocrit levels than females.
Half of the individuals were divorced and the other half was widowed. The study found that widowed individuals showed a higher life satisfaction before than after, whereas the divorced group showed the opposite result. Research into life changes can be criticized for being correlation they therefore cannot imply causality, there also may be other factors to consider such as depression and chronic physical illnesses which may lead to life problems rather than be caused by the. Rahe’s study had a correlation of 0.118 which isn’t very strong as a per correlation has a correlation of 1. Rahe’s study can also be deemed as androcentric and ethnocentric.
Provide a rationale for your answer. Discuss the meaning of this result in this study. Yes t=-1.99 is significant because the p=0.049 value is smaller than alpha (a) that was set at 0.05 for this study. From the study, this means that there is a significant difference between the results obtained from men and women since this is one of the values that allows the selected hypothesis to be correct, the significance is support to the performed experiment. 4.
Gershon et al. (1989) research supports this view. In his research, Gershon found that there was a concordance rate (the proportion of pairs where both individuals share a certain characteristic) between family members and the risk of developing depression; he concluded that the more genes individuals share, the more likely they are at developing depression. However, this piece of research could be argued against as it claims that identical (MZ) twins only have a 55% chance of inheriting depression. However, if MZ twins share 100% of their genes, then they should both have 100% chance of developing depression, but according to this research, that is not the case; this research may also suggest that genetics are not the main factor in developing depression.
The following is my evaluation of Table 3.1 Data: The education predictor has very low correlation with citizenship and absence measures. Citizenship is shown to be positive and absence is shown to be negative; however, they are both close to 0. On the contrary, the correlations between education and the performance and promotion potential are slightly higher than citizenship and absence, but they are still undesirably low. Out of these 4 measures, the correlation between education and promotional potential is considered to be the highest because education can definitely predict a future employee’s promotion potential. Promotion potential has a p value of <.01 which makes it statistically significant.
Further support comes from Kohler et al (2002) who gave particpants 50 words and measured the galvine skin resistance (GSR) for the levels of stress. He found that words with a high level of GSR were the words that were most anxious and worst remembered. However there may be some ethical issues as participants may have thought that there may be harm in the GSR but the fact that there was no complaints suggests that is was ethical. The tests carried out were objective which is a much more reliable and valid way of measuring that subjective techniques like self-report measures which may have demand characteristics. On the

Most studies of spousal caregiving report that husbands experience lower levels of burden than wives, and the husbands are also more likely than wives to receive supplemental assistance (National Alliance for Caregiving). Marital status of the individual receiving care is an importance factor, since
