A correlational study examined the relationship between a large group of students' overall achievement and their level of self-confidence. The results were reported as statistically significant (r = .17, p. = .01). With what should you be concerned?
a. The theoretical importance of this study |
||
b. The lack of statistical significance of the results |
||
c. The lack of practical significance of the results |
||
d. The sample size |
The lack of practical significance of the results.
see the correlation value is small but not zero and result is statistically significant it mean there exits some degree of relation between these two variables.
It is never appropriate to conclude that changes in one variable cause changes in another based on correlation alone. Only properly controlled experiments enable you to determine whether a relationship is causal.This means practical significance of the results is still questionable.
Also correlation is weak.
So whether self confidence causes achievement to improve is not conclusive as of this result alone.
