- A researcher is investigating the effectiveness of two weight loss treatments. The number of patients attending Treatment A and Treatment B are 30 and 32 respectively. The patients’ weight losses (in Kg) after a two-month treatment period are recorded and shown in Table 1: What type of research design you think this research should be classified? Explain your answer. Based on the research objective of the study, identify the: Independent and dependent variables of this research. Scale of measurement of each of the independent and dependent variables. For EACH of the treatment, determine/construct the following measures and histograms of weight losses using SPSS or any suitable statistical analysis tool: Mean Median Range Histogram d. Based on the histograms of weight losses produced in (c), briefly describe: The shape of distribution of weight losses for EACH treatment. How does the distribution of Treatment A differ from Treatment B e.…arrow_forwardRead through this scenario and look at the data that was collected. State the null and all possible research hypotheses. Review the results below (I used SPSS) and answer the questions that follow. Scenario: A researcher wants to see if gender and / or income affects the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables…arrow_forwardRead through this scenario and look at the data that was collected.

- Does the presence of a significant interaction change the interpretation of significant main effects? Provide one example including a minimum of two independent variables.arrow_forwardA researcher conducts and independent- measures study examining the effectiveness of a group exercise program at an assisted living facility for elderly adults. One group of residents is selected to participate in the program, and a second group serves as a control. After 6 weeks, the research records a combined score measuring balance and strength for each individual. The data are as follows: Control Exercise n = 10 n = 15 M = 12 M = 15.5 SS = 120.5 SS = 190.0 %3D 1. Does the exercise program have a significant effect? Use an alpha level of .05, two tails. Show all calculations. a. State the research hypotheses b. Identify the critical value c. Calculate the test statistic d. Evaluate the null hypothesis 2. Compute Cohens d to measure the effect size of the treatment.arrow_forwardYou may need to use the appropriate technology to answer this question. An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. Because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. The data obtained follow.

- What are the requirements for an experiment to be able to show that changes in one variable cause changes in another?arrow_forwardSeedlings 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?

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.
