A researcher determines that there is a 0.038 correlation between time spent on a cell phone, and the hours of sleep you get each night. Based on the value presented (0.038), is there a correlation between phone usage and sleep?
Homework Answers
Correlation ranges from -1 to 1
-1 : Perfect negative correlated
1: Perfect positive correlation
0: No Correlation
Since the value 0.038 is close to zero. it shows there is no correlation (approximately).

A correlation tests whether differences exist between two variables. Question 1 options: a) True b) False Question 2 (1 point) You have tested to find whether a relationship exists between hours of sleep the night before an exam and grade on the exam. You have a participant pool of n = 30, df = 28. Your hypothesis is that a significant relationship will exist, where those with more hours of sleep receive higher grades on the exam. This is a...
