Social Work Research

Chapter 9:

  1. How sampling theory assists in the process of social work research. Why it is used in most studies? Explain in detail and provide as many examples to justify your response. (pp. 191-192).

Sampling theory helps in the general collection of data about the study or research of a given population. The research is defined hence the necessary steps will be taken to undertake the research; the sampling theory helps the researchers on the steps and procedures that they will use in order to capture the required information.

2. List and briefly discuss the different types of probability sampling procedures. Provide as many examples as you can to justify your response. (pp. 192-197)

  1. Simple Random Sampling: it used where there are a given number of samples and the numbers are chosen in such a way that every set is given an equal chance that will be chosen as a sample.  For example, collection of pages in a book pages are just selected randomly.
  2. Systematic Random Sampling: the size of the population is usually divided by the desired sample size so that a desired sampling interval can be reached. It uses the same principles as simple random sampling; it is used to select large samples from a long list of given elements.  
  3. Stratified Random Sampling: Researcher divides the entire population into different sub groups called strata, after the division randomly selects the final samples proportionally from the different subgroups.
  4. Cluster Random Sampling: the researcher takes several steps in gathering the information needed, the population is divided into clusters then a simple random sample is obtained from all possible clusters finally obtain data on every sampling unit of the randomly selected clusters.

Chapter 10:

1. List and discuss in detail the three explanatory single-subject designs. Provide a social work example of each. (pp. 210-222).

  1. ABA and ABAB Designs: It begins with an assessment phase whereby there is no intervention; there are repeated withdrawals of intervention which strengthen the research.
  2. BAB Design: this design begins with the intervention phase and is useful for crisis problems.
  3. BCBC Design: in this design the assessment phase is not included. B intervention followed by C intervention twice in succession and used to prove one intervention is better than the other.

Chapter 11:

  1. Out of all the one-group-level designs presented in this chapter, which one do you think is used most often in social work research? Why? Justify your answer. Which one do you think is least utilized? Why? Justify your answer. (pp. 237-244).

Longitudinal Design can be the most effective to use in the social work research. The reason being it is involved in various stages of measurements before coming up with a conclusive decision. It involves trend studies, cohort studies and finally panel studies. Due to its intensive research, data collection and verification I take it as an ideal design to use it in social work. In One group post test on my opinion should be the last option since the research done is very brief and facts are hard to represent.
