- Summarize the advantages and disadvantages of qualitative research when compared to experimental or survey research? Under what circumstances would a researcher choose a qualitative design?arrow_forwardAs you read about each study, (a) classify the type of research that it reflects, and (b) identify the kinds of conclusions that might reasonably be drawn from the results. During their 8th- and 11th-grade school years, students in the Ranger School District take standardized achievement tests designed to assess their language and math skills. The superintendent receives a report showing how Ranger students compare with those in many other school districts across the nation. The superintendent discusses the results with the school principals. (a) Classify the research as one of the following: Quantitative/descriptive Quantitative/correlational Quantitative/experimental Quantitative/quasi-experimental Qualitative Mixed methods, and then (b) Identify one or more conclusions that might reasonably be drawn from this study and, if relevant, one or more conclusions that cannot be drawn from the studyarrow_forwardMandrake Falls High School is experimenting with a weekend course in laboratory techniques. Of the 200 students enrolled in lab classes at Mandrake, only 78 have been able to take the techniques course. Mandrake is interested in evaluating the course's effectiveness in propagating safety in the laboratories. During regular lab classes, lab instructors have recorded harmful lab incidents: accidents, misuse of lab equipment, etc. The school is looking at the data and examining two variables: laboratory performance ("involved in no incident", "involved in exactly one incident", or "involved in 2+ incidents") and status regarding lab techniques course ("took the techniques course" or "didn't take the techniques course"). The contingency table below gives a summary of the data that have been gathered so far. In each of the 6 cells of the table are three numbers: the first number is the observed cell frequency (f); the second number is the expected cell frequency (E) under the assumption…arrow_forward
- Seedlings of an annual plant were split into two equal treatment groups; in one group, extra fertilizer was provided, and in the other group (the control group), no additional fertilizer was added. The numbers of seeds and the average weight of the seeds from each individual plant were monitored, and these data were plotted (each point represents an individual plant). Which statement best describes the results of this study? Control With fertilizer 450 400 400 350 350 300 300 250 250 200 200 130 130 100 100 50 50 10 20 30 40 50 70 10 20 30 40 50 Number of seeds Number of seeds O A. Trade-offs between seed size and seed number exist in both the control and the fertilizer groups, and these trade-offs are of roughly equal magnitude. B. Trade-offs between seed size and seed number exist in both the control and the fertilizer groups, but these trade-offs are much larger in the fertilizer group.

First, due to the cross-sectional nature of our study, causality cannot be inferred.” Explain what this statement means and why it is an issue.arrow_forwardYou are the manager for a family medicine clinic that has 3 physicians. The staff have come to you with an informal observation that there are differences in the number of patients that each physician is seeing each day. As manager, it is your job to make management decisions based on unbiased data. In order to evaluate the situation you collect the number of patients seen by each physician for a 5 day work week. Your observations are provided in the table below. In order to see if there is a significant difference you need to conduct an ANOVA test.

- You are an analyst for a small chain store and are told to check if any of the five stores are outperforming the other stores. You send out your survey teams and gather the following data: Range Jan - Mar Apr - June Jul - Sep Oct - Dec Group Problem Data (Franchise Performance) Store 1 Store 2 3 3 2.4 4 6 2 3.8 7.1 Store 3 2.8 3.2 4.1 7.9 Store 4 3.1 2.9 5 7 Store 5 3.2 3 2 6.6 Perform the ANOVA test and explain to the group if any of the stores outperform the others. Explain how you arrived at your answer. Be sure to share how you arrived at the null and alternative hypotheses, any mistakes you made during the analysis, and discuss the results. Hint: Your p-value is 0.966.arrow_forwardThe effect of aid is a subject of considerable academic and policy interest. In this question we examine the relationship between foreign aid and civil conflict using a recent paper by Crost et al. (2014) in the Philippines. The authors collect data on civil conflict related incidents at the municipality level as well as information on aid receipts at the municipality level. The conflict data was collected from the Philippine military and provides casualty counts (as well as the party responsible) by municipality. Aid in this context refers to a large anti-poverty program (the KALAHI-CIDSS) funded by the World Bank and run from 2003-2008. The program provided cash grants to municipalities to build infrastructure such as roads, water-systems, clinics and schools. The grants were fairly large and accounted for approximately 15% of the annual budget for the average municipality. (a) Let Yi denote the number of conflict casualties in municipality i in a given timeperiod after the…arrow_forwardIf I studied the relationship between class size and student achievement, what kind of research design would I use?arrow_forward
