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

Answer #1

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.

Research Scenario: Is there a positive relationship between grit and GPA in high school seniors? A researcher examined this issue by having students beginning their senior year of high school complete a grit inventory using a Likert-based scale (range 1 – 7), where higher numbers indicate more “grit”. GPA was self-reported (scale 0 – 4.0). Enter the data shown here into SPSS to assess whether there is a positive relationship between grit and GPA. Grit GPA 6.5 4.0 4.0 3.1...

Belmont and Marolla conducted a study on the relationship between birth order, family size, and intelligence. The subjects consisted of all Dutch men who reached the age of 19 between 1963 and 1966. These men were required by law to take the Dutch army induction tests, including Raven’s intelligence test. The results showed that for each family size, measured intelligence decreased with birth order: first-borns did better than second-borns, second-borns did better than third-borns, and so on. And for any...
