Correlation coefficient testing and R-square value
A Study was conducted with α = 0.01 to conclude if there is significant linear correlation between the number of credits hours earned at the same time of taking Statistic 101 and grade in the course. Ten pairs of data were collected. The linear correction coefficient is r = 0.884
Select the correct conclusion.
a) There is significant linear correlation
b) there is not a significant linear correlation
Resolve the proportion of variation in grade that can be explained by linear correlation between the grade and the number of credit hours earned at the same time of taking the course. _______________ (nearest hundredth).
