Suppose that students who work fewer hours at their jobs tend to have higher grade point averages and they also tend to get more sleep.What would the correlation coefficient be if we were to correlate the two variables of grade point average and number of hours of sleep

A)  greater than 1, but less than 2 
B)  equal to 0 
C)  less than zero, but greater than -1 
D)  greater than 0, but less than 1

Correlation Coefficient

A numerical indicator that demonstrates how significantly two variables move in tandem, highlighting the intensity and orientation of their connection.

Grade Point Averages

A numerical representation of a student's academic performance, typically on a scale from 0 to 4.0, used by educational institutions to measure overall achievement.

Hours of Sleep

The duration of sleep an individual gets, crucial for health and well-being, affecting cognitive function and physical health.
