Hlt 362-V Exercise 11 & 16

·  How were measures of variation used in the study? What conclusions can you draw based on the variation?

1. The researchers analyzed the data they collected as though it were at what level of measurement?- The correct answer is Interval/ratio.

Part B: How might each of the following concepts affect the results of the study?

The authors reported multiple df values in Table VI. Why were different df values reported for this study?

2. What data and method does the author use to evaluate this intervention? Why was that data and method used?

C. The researchers analyzed the data as though it were at the interval/ratio level since they calculated means (the measure of central tendency that is appropriate only for interval/ratio level data) and standard deviations (the measure of dispersion for interval/ratio data) to describe their study variables.

1. Describe the context (why it was done, the general interest and what the researchers wanted to find out) of the research and research question (what is the hypothesis). /10

2. What statistics were used to describe the length of labor in this study? Were

4. Were the distributions of scores similar for the experimental and control groups for the length of labor? Provide a rationale for your answer.

Age, Income, Length of labor, Return to work and number of hours working per week.

Although the research by Michalak et al. mainly focused on chronic depression, the article still provides appropriate information about effectiveness of depressive treatments. It accomplishes this, by comparing and contrasting certain treatments (MBCT, CBASP, TAU) targeted at the psychological disorder of depression. It also describes the certain tools that are used (HAM-D, BI, SASS) in order to measure and analyze the viability of these treatments. Furthermore, the article describes and proves how CBASP is predominately the main treatment for chronic depression.

While reading the description of the study, one can easily identify various confounds within. First, the study that lasted for 9 months and had initially 50 participants had no control group. In any experimental research design, the need in two or more groups, from which one is the “control” group, is necessary to have a valid research conclusion. Next, what is the definition of depression in the study? And who determined whether these 50 participants had the given condition: was it a requirement to have a licensed physician diagnosing them with the condition or the participant had to just identify himself/herself with being depressed? Third, while there were 50 participants in the beginning and by the end of the study only 29 remained, from which 85% demonstrated some improvement, does it mean the other 21 participants that dropped from the study had their condition worsened?

The researcher wishes to estimate the population means for the two variables under consideration using the sample data.

1. What would this study have to look like in order for it be predominately qualitative?

This chapter will focus on the research design, study area, study population, sample size and sampling procedures, data collection instruments, validity and reliability of data collection instruments, data analysis techniques and ethical considerations.
