Question

mr. george conducted a study in which he measured the time his physics students spent on his online course modules in comparison to their overall class average. he then graphed his findings using a scatterplot. what type of correlation did mr. george find as a result of his study?
a no correlation
b negative correlation
c positive correlation
d illusory correlation

Explanation:

A positive correlation means that as one variable (time spent on online course modules) increases, the other variable (overall class average) also increases. It is logical to assume that more time spent on learning materials (online modules) would lead to better understanding and higher grades (class average). A negative correlation would mean one goes up as the other goes down (e.g., more time on modules but lower grades, which is counter - intuitive here). No correlation would show no pattern in the scatter - plot. An illusory correlation is a perceived but not real correlation. Since the relationship between study time and grades is a real and positive one in general.

Answer:

C. positive correlation
