RESULTS

Let's go back to our survey.

We want to look for a link between two variables of our study.

1.- we want to see the link between

- Number of subjects the student failed

- Number of hours the student study

2.- We want to see the link between

- Number of subjects the student failed

- How the student score the school (number)

If we make all the statistics calculations (correlation coefficient r) and the graphical representation using the results spreadsheet we see the following:



r = -0,304



r = -0,127
