Calculate the correlation coefficient and briefly characterize the correlation in words.

r=______

?(Round to two decimal places as? needed.)

City Mean daily high temperature for January (ºF) / Mean January precipitation (inches)

1        54                                               2.5

2         88                                             0.4

3        36                                                1.9

4          55                                            5.4

5        44                                              2.3

6        21                                            4.1

7        30                                          2.0

8       54                                          3.6

9        47                                              2.2

10     34                                                1.8

correlation = - 0.30

This means that there is a weak negative linear relationship between a City Mean daily high temperature for January (ºF) and Mean January precipitation (inches).

Therefore, City Mean daily high temperature for January (ºF) and Mean January precipitation (inches) moves in opposite directions. As City Mean daily high temperature for January (ºF)increases, Mean January precipitation (inches) decreases by 0.30

Step-by-step explanation

To calculate the correlation coefficient, excel was used by use of a CORREL function and the output

From the output, correlation = - 0.30

This means that there is a weak negative linear relationship between a City Mean daily high temperature for January (ºF) and Mean January precipitation (inches).

Therefore, City Mean daily high temperature for January (ºF) and Mean January precipitation (inches) moves in opposite directions. As City Mean daily high temperature for January (ºF)increases, Mean January precipitation (inches) decreases by 0.30
