Review of Research Literature - Assignment Example

Review of Research literature 16. White et al: a. What measure of central tendency for Age is reported in Table A4 What is the level of measurement for this variable? What measure of variability is reported for this variable? What are the values for these descriptive statistics? The variability measure of central tendency for age is reported. Standard deviation has been included while providing baseline characteristics of participants. Age related descriptive statistics measures for participants include the mean age with standard deviation. The mean age of male participants is 56.8 with standard deviation(SD) 15.3, and that for female is 73.6 with SD 11.2. b. What inferential test was done to test changes over time of caregiver characteristics (Table A4-2)? Is this test parametric or non-parametric? Does Physical Function change over time at a statistically significant level (compare the p-value to the alpha level)? Inferential statistics allows researchers to generalize findings from a sample size to that of an entire population with a certain amount of confidence regarding the research findings. To estimate the stress associated with care giving Burden Index, a 22-item measure, has been completed by caregivers. Burden index is designed to assess feelings of anger, frustration, and stress as well as the burden of being a caregiver. This is a parametric test because ‘t-tests’ were used to compare variables. The data analysis showed that social function (SF) subscale (SF-36) increased significantly between the first and second years of care giving and the probability error value (p-value) is given as p Read More
