Research question: Does homework average have an existing correlation with the quiz average of students?

Explanatory variable (x): Homework Average       &      Response variable (y): Quiz Average

The correlation coefficient between these two variables was 0.55951575. This means that there actually is very little to no correlation beteen the explanatory variable of HW average and the response variable of Quiz average. As for strength, this scatterplot and the relation it has between the variables, hold no strength but can show a clear positive direction.

Answer to research question: With the evidence and correlation coefficient collected from this data, it is safe to say that HW average (as the explanatory variable) has no existing correlation to Quiz Average (as the response variable) of students.

Lurking variables: 

  • amount of units/course each student is taking
  • time management
  • access to tutoring
  • personal family issues
