a. What was the purpose of this study?
b. Why was a survey design appropriate for this study as opposed to another design such as experimental or quasi-experimental design?
c. What type of survey was used in this study?
d. How did the researcher select a probability sample?
e. How did the researchers approach the issue of generalizability in discussion of their study?
f. What are the standards of quality for survey research?
g. Do a similar evaluation summary for the Mokhtari et al. (2009) survey study. You may use this table:
Criteria from Table 18.1 (Jaegerâs 1997 criteria)
Mokhtari et al. (2009) study
Research questions (items 1-3)
Sampling and response rates (items 4-11)
Instrumentation (items 12-18)
Data-gathering procedures (items 19-20)
Analyses and conclusions of report (items 21-26)
h. What type of statistical analysis was used in this study?
i. Do you have any other critiques of this study?
j. Based on your educational setting and/or personal research interests, what type of survey might you yourself employ? Why would a survey be the best way for you to find out that information/address that research question?

empowerment of women: Impact of a functional literacy program in Turkey.

a___Based on the literature review in this study, how do the authors make the case for the importance of their study?
b___How would you articulate the hypotheses for this study through description of the null and alternative hypotheses? Provide for each hypothesis in the study.
c___What research designs were used in Study 1 and Study 2? Provide rationale for your answer.
d___Explain why t-tests were used in the data analyses for these studies. What did t-tests allow the researchers to find out to address their hypotheses?
e___Did the researchers use one- or two-tailed t-tests? Why?
One-Way ANOVAs
III-Calhoon, M. B., Al Otaiba, S., Cihak, D., King, A., & Avalos, A. (2007).
Effects of a peer-mediated program on reading skill acquisition for two-
way bilingual first-grade classrooms. Learning Disability
Quarterly, 30(3), 169â184. (see the attached doc)
a) Now that you gained some experience with literature reviews, provide some commentary on the literature review in Calhoon et al. (2007). For example, you can discuss several things: you might discuss how the literature review supports the importance/relevance of the topic, how the literature review is organized thematically, how the literature review narrows and points to a gap in the research.
b) What research method was used in this study? Why is it appropriate for the research questions?
c) A one-way ANOVA was used as one of the analyses in this study. Pinpoint that part in this article and discuss. What question was the one-way ANOVA used to answer? Provide other observations about the test (e.g., what was the p value? what does that mean?) Why are the results of this ANOVA relevant?
d) What do you find important or interesting about the outcomes of this study?
