Question

investigative question, variables, number of variables

1. is there a correlation to a students preferred genre of movie and their current grade level? variable #1: categorical or numerical variable #2: categorical or numerical univariate or bivariate
2. what is the average number of books read by students over the summer? variable #1: categorical or numerical variable #2: categorical or numerical univariate or bivariate
3. how does the number of hours spent on social media each day relate to the number of hours of sleep a student gets at night? variable #1: categorical or numerical variable #2: categorical or numerical univariate or bivariate
4. how does the average amount of time spent on physical exercise per week relate to students self - reported stress levels? variable #1: categorical or numerical variable #2: categorical or numerical univariate or bivariate

Explanation:

Step1: Analyze question 4

Variable #1: Preferred genre of movie is categorical. Variable #2: Current grade - level is categorical. Since we are looking at the relationship between two variables, it is bivariate.

Step2: Analyze question 5

Variable #1: Number of books read is numerical. There is only one variable to consider to find the average, so it is univariate. Variable #2 is not applicable as it is a single - variable analysis.

Step3: Analyze question 6

Variable #1: Hours spent on social media each day is numerical. Variable #2: Hours of sleep a student gets at night is numerical. Since we are examining the relationship between two variables, it is bivariate.

Step4: Analyze question 7

Variable #1: Average amount of time spent on physical exercise per week is numerical. Variable #2: Self - reported stress levels can be considered numerical (if on a rating scale). Since we are looking at the relationship between two variables, it is bivariate.

Answer:

1. Variable #1: CATEGORICAL, Variable #2: CATEGORICAL, UNIVARIATE or BIVARIATE: BIVARIATE
2. Variable #1: NUMERICAL, Variable #2: N/A, UNIVARIATE or BIVARIATE: UNIVARIATE
3. Variable #1: NUMERICAL, Variable #2: NUMERICAL, UNIVARIATE or BIVARIATE: BIVARIATE
4. Variable #1: NUMERICAL, Variable #2: NUMERICAL, UNIVARIATE or BIVARIATE: BIVARIATE
