Question
I would like to know if I answered correctly these two questions above. Thank You in advance!
Question # 3 A) Given the problem: How well can scores on the OLI Checkpoints be predicted by the number of OLI activities completed?a. What is the explanatory variable? What type of variable is it?
b. What is the response variable? What type of variable is it?
c. What would be an appropriate visual display for examining the relationship between these two variables? Answers: a. The numbers of activities completed by the studente is the explanatory variable, and it is quantitative. b. The score predicted is the response variable, and it is quantitative. c. The appropriate visual display for the relationship for these two variables would be a scatterplot. Therefore, questions a and b are example case QQ. B) Given the problem: How do the OLI Checkpoint scores of the males in this class compare to those of the females?
d. What is the explanatory variable? What type of variable is it?
e. What is the response variable? What type of variable is it?
f. What would be an appropriate visual display for examining the relationship between these two variables? Answers: d. The gender is the explanatory variable, and it is categorical. e. The checkpoint score is the response variable, and it is quantitative. f. The appropriate visual display for examing these two variables would be side by side boxplots. Therefore, questions d and e are an example of case CQ.
Explanation / Answer
A) How well can scores on the OLI Checkpoints be predicted by the number of OLI activities completed?
a) Number of OLI activites completed is explanatory variables. It is quantitavive variable.
b) Scores on the OLI checkpoints is responce variable and it is quantitative variable.
c) The appropriate visual display for examining the relationship between these two variables is scatterplot.
B) How do the OLI Checkpoint scores of the males in this class compare to those of the females?
a) Explanatory variable is gender as the scores are compared on the basis of gender as male and female. It is categorical variable.
b) OLI checkpoints scores is responce variable, which is qualitative variable.
c)The appropriate visual display for examining relation between these two variables is Boxplot.
