Question

6. For each of the following scenarios, simply state WHICH technique that you have learned this semester would be the most appropriate method to ana (e.g., directional?) (10 points) lyze the results. BE AS SPECIFIC AS POSSIBLE A. Sa m wants to know if people spend more time studying for their midterms or their finals She asks 30 people how many hours they studied for each test, and records their responses She thinks people probably spend more time studying for finals. 8. Then, Sam decides to take things one step further and wants to know if how much time one spends studying for the midterm significantly predicts how much time one will study for the final. pre dicion C. Michael thinks that pecple who travel more report higher quality of life. To test this Michael studies a group of 20 people across many years. He gets them to rate their quality of life (on a scale from 1-10) beícre they've travelled at all, again after they've taken their first trip abroad and again after they've taken their fifth trip abroad. Michael compares the data at the three time points to see if his hypothesis is correct. Repeated st , sono Yop Meredith wants to know if a new medication affects sleep. So, she takes a sample of 81 people and has them all take the medication for a week. During that time, those 81 people record the number of hours they slept. If you are given M-42,-45 and o-10, how can you determine whether the medication affects the number of hours people sleep. D. In the previous question, if I gave you the standard deviation for the group of 81 people, instead of = 10, what would you do to answer the same question? E.

Explanation / Answer

Note: This response is in UK English, please paste the response to MS Word and you should be able to spot discrepancies easily. Also, I apologise as I could not answer “E” as that is a question in statistics and not psychological research. If you have any other doubts, please leave a comment below.

(Answer) (A) Sam should conduct two tests in his research methodology. Firstly, interview the test subjects and tally the hours they claimed to have studied. Secondly, check the test subjects’ scores and check if the aggregate scores of mid-terms or finals are higher. Taking both results in empirical values, Sam should apply a correlation coefficient method.

(B) Considering that an individual’s GPA is the sum of scores throughout the year. Sam will be able to predict that if a student scores poorly for the mid-term they are more likely to study harder for the finals. Sam could support his hypothesis by keeping a record of the students’ scores.

(C) Apply the Linear Regression Model. It is befitting to this case where the relationship between the dependent variable is analysed with one or more explanatory variables.

(D) By comparing the results with the sleep patterns before medication and checking the difference in the dependent variable (in this case, the sleep is the dependent variable.)

(E)
