The researcher should use a factorial ANOVA analysis to examine the effects of mode of presentation, type of study, and having a study guide on test scores.

Step 1
In this case, the independent variables are mode of presentation (e.g. online vs. in-person), type of study (e.g. experimental vs. observational), and having a study guide (e.g. yes vs. no). Show more…

Question 27-30: A psychologist recruits 30 students to participate in an experiment. The plan is to randomly divide the students into groups to be given one of three versions of a memory test. Half the students will be given a quiet environment to take the test, and half a distracting environment. That is, the plan is to have five students in each Test/Distraction combination. However, two students misunderstand the instructions and their data has to be discarded. 27. In this context, construct the ANOVA model. Including the definition of all terms and subscripts. 28. Finish filling in the ANOVA table below. Source | df | SS | MS | F ---|---|---|---|--- Model | | 92 | | Test | | 15 | | Distraction | | 69 | | Test*Distraction | | 17 | | Error | | | | Total | | 174 | | 29. Use the appropriate statistical procedure to test the overall ANOVA model.

A total of 100 undergraduates were recruited to participate in a study on the effects of study location on learning. The study employed a 2 x 2 between-subjects design, with all participants studying a chapter on the science of gravity and then being tested on the to-be-learned material one week later. Fifty of the participants were asked to study the chapter at the library, whereas the other fifty were asked to study the chapter at home. As a separate manipulation, participants were either told to study the chapter for 30 min or 120 min. The hypothetical set of data shown below represents the level of performance of participants on the test as a function of condition. 30 min 120 min Library 60 80 Home 40 60 a) Is there a main effect of Study Location? In answering, provide the marginal means and state the direction of the effect (if there is one). b) Is there a main effect of Study Duration? In answering, provide the marginal means and state the direction of the effect (if there is one). c) Do the results indicate an interaction? If so, describe the nature of the interaction by comparing the simple effects. d) Illustrate the results with a bar graph (make sure the variables and axes are labeled appropriately) e) Interpret the results. What do they tell you about how study location affects learning? (be sure to refer to the interaction or lack thereof)

Thirty people took part in a study to see the extent to which musical ability is related to math proficiency. The researchers observed each subject as they played piano and scored their proficiency with the piano. Subjects also took a math test. Two sets of scores were then analyzed to determine if the two skills were related. Which of the following research designs was used in the study? [Controlled] experimental study using self-reported data. Non-experimental study using self-reported data. Non-experimental study. [Controlled] experimental study.
