Question

Correlation - Do you think there would be a positive correlation between a placement test score and the final grade in this statistics class? What other variables do you think would have a positive correlation with the final grade in this (or any) class? What variables would have a negative correlation with a final grade in a class? Look up a study that finds a correlation between grades and some other variable. Describe the variables, the study, the methods used, whether the correlation is positive or negative, and how this relates to your life.

Answer 1

Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer

There would be a positive correlation between a placement test score and the final grade in this statistics class. Because its natural that the higher you score in tests , the more brighter you are, and chances that you will score good in final grade in statistics class are more.

Hence, YES

Other variables influencing :

Positively: Attendance, Time spent to learn statistics, back ground in statistics, background in basic mathematics, has the student taken a Statistics prep course before this statistics class, average scores in other subjects : More positive these are, there may be a positive correlation of these variables with Final grade in statistics.

Negatively: Number of statistics class bunked, playing time of a student, number of detentions, score in art class : These variables if high may negatively correlate with Final Grade in Statistics.

Study:

Here' a study which relates tests the following hypothesis - something similar to what' asked in the question.

Research Question 1: What is the nature and strength of the relationship between student participation (volume) and actual student achievement in online learning?

Research Question 2: What is the nature and strength of the relationship between the frequency of student attendance and actual student achievement in online learning?

Hence, the hypothesis became:

Hypothesis 1 H1: There is a positive relationship between the volume of student participation and student achievement in an online learning course and the final course grade.

Hypothesis 2 H2: There is a positive relationship between the frequency of student attendance and student achievement in an online learning course and the final course grade.

The variables were:

Final grade = GPA

There were two predictor variables used in this study.

The first predictor variable was the number of times (volume) the student logged into the Learning tool.

The second predictor variable identified student attendance. Student attendance was determined by the number of days (frequency) the student logged into the Learning tool.

data background : The sample used in this study was 548 undergraduate online students from 34 online courses

They conducted correlation analysis method to check

Conclusions :

1. There are beneficial effects of online participation in terms of widening student involvement and improving the quality of online discussions as well as research on the beneficial effects of online interaction in terms of fostering an online community. - Positive Correlation

2. They also found levels of attendance and online access serve as important predictors of performance and attendance - Positive Correlation

3. Hit consistency (regular hits to the online tool ) in a web-augmented course was positively associated with course grade- Positive Correlation

4. Hits within content areas and greater student usage of tools in content areas positively affected students’ final course grades - Positive Correlation

5. requiring student interaction just for the sake of interaction might lead to diminished completion rates - Negative Correlation

6. research also indicates that increased levels of interaction, as measured by time spent, actually decrease course completion rates - Negative Correlation
