1. The correlation coefficient determined for two variables has
a value of 0.89. Describe, in words, the
correlation between the two variables.
2. The correlation coefficient determined for two variables has
a value of 0.13. Describe, in words, the
correlation between the two variables.
3. The correlation coefficient determined for two variables has
a value of -0.93. Describe, in words, the
correlation between the two variables.
Homework Answers
Answer:
1) Since, r = 0.89
so we say that these is strong positive correlation between two variables .
2) Since, r = 0.13
we say that these is weak positive correlation between two variables .
3) r = -0.93
we say that these is strong negative correlation between two variables .
