Answer:
The value -0.7 represents the strongest negative correlation.
Step-by-step explanation:
The correlation coefficient r determines how strong the correlation between two statistical variables is.
It can indicate a direct or inverse relationship between variables.
Its value ranges between -1.0 and 1.0, the closer its value is to these two values, the greater the correlation between the variables.
Therefore, sorting the data from the smallest to the largest you have:
-0.7 -0.22 0.38 0.9
As you can see the largest negative value is -0.7, therefore the value -0.7 represents the strongest negative correlation.
