Instructions

Read these instructions carefully before you begin and plan to refer back to them as needed for information about the variables. Open the data in Assignment 2 data.csv into jamovi. This dataset includes data collected from 100 adults who participated in a study about aging and physical well-being. Information was collected from these participants regarding various factors related to physical fitness and health, including:

Activity level. How active participants are: either "Sedentary" or "Active."
Age.How old participants are: either "Younger than 50" or "50 or older."
Pet Ownership.What kind of pet does each participant own: "Cat," "Dog," "Other," or "No pets."
Sleep.How much sleep each participant typically gets per night: measured in number of hours.
Resting HR.Participants' heart rate measured at rest (i.e., baseline, before workout), in beats per minute.
Post Workout HR.Participants' cardiovascular reaction to exercise,heart rate measured immediately after completing a high intensity workout, in beats per minute.

For each question you will need to:

Identify the variable or variables in the dataset that match the described research scenario
Choose the statistical approach (i.e., hypothesis test) that is appropriate given the described research scenario
Run the chosen statistical analysis in jamovi (including any necessary assumption tests; note that for the purposes of this assignment simply note any violations to assumptions you may identify, but then proceed with the analysis)
Make a decision about the null hypothesis(es) underlying your analysis
Provide a detailed conclusion interpreting the results of each hypothesis test back to the research scenario using the format modelled in class examples and practice problems
Answer any additional questions asked of you (where applicable)

Question 1 [15 marks]

The researchers want to know if activity level affects participants' cardiovascular reactions to intense exercise and if this effect depends on participant age.

a) What statistical approach (hypothesis test) should be used for this scenario? Why? (1 mark)

b) Run the statistical analysis in jamovi. Be sure to include in your answer to this question:

(i) output from any assumption tests needed as well as statements as to whether the assumption(s) were met, and the evidence used to make these decisions (proceed with your analysis even if assumptions are violated). (4 marks)

(ii) full output of the main analysis including any necessary follow up tests. (3 marks)

c) Make a decision about the null hypothesis(es) tested in your statistical analysis and briefly explain the evidence you used to make this/these decision(s). (3 marks).

d) Provide a conclusion of your analysis that interprets the results and relates them back to the research context using the conclusion write up format taught in class (4 marks)
