Question 986106: Alex puts his spare change in jar every night. If he has $11.09 at the end of January, $22.27 at the end of February, $44.35 in April, $75.82 in July, $89.00 in August, and $114.76 at the end of October, perform a linear regression on this data.
What does the value of the correlation coefficient tell you about the correlation of the data?

You can put this solution on YOUR website! Alex puts his spare change in jar every night. If he has $11.09 at the end of January, $22.27 at the end of February, $44.35 in April, $75.82 in July, $89.00 in August, and $114.76 at the end of October, perform a linear regression on this data.
y = 11.34x - 0.897
correlation coefficient:: r = 0.9992
----------------------------
What does the value of the correlation coefficient tell you about the correlation of the data?
There is a very strong linear correlation between the month and the
amount of change in Alex's jar.
