Question

IS R SIGNIFICANT IF R=0.85, N=10

Answer 1

r is the correlation coefficient (tells us the strength of the relation)

N= 10 data points.

df=N-2= 8

The critical values associated with df= 8 are -0.632 and + 0.632.

If r < negative critical value or

r > positive critical value, then it is significant.

r=0.85

Therefore, r> 0.632

As r is greater than positive critical value it is significant.
