QUESTION 2
a. Interpret the correlation coefficient
The correlation coefficient (r = 0.66) indicates a moderate to strong positive
relationship between student participation in online discussions (X) and their final
examination scores (Y). This means that higher participation in online discussions
tends to be associated with better final examination performance. However, since
the correlation is not close to 1, the relationship is not perfect, but it does suggest
that increased participation likely contributes to improved exam scores.
b. Percentage of common variance
c. Calculate the slope.
