Question

Dr. English develops a test that she believes will predict the academic success of college freshmen. Dr. English finds a correlation coefficient of .70 between high-school seniors' scores on the test and their freshman GPAs one year later. What can one conclude regarding Dr. English's test?

Answer 1

Answer:

Dr. English's test is a good predictor of the academic success of college freshmen                  

Explanation:

In correlation studies, a coefficient of 0.70 is an indication that the variables under consideration (Dr. English's test score and Academic success of freshmen college students) are strongly and positively correlated. That is, an increase in one variable will result in an increase in the other variable, there is a strong positive association between both variables.

Since the correlation coefficient between Dr. English's test score and academic performance of college freshmen is 0.70. It means that both have a strong, positive correlation/association. That is a higher score in Dr. English's test will result in a higher academic performance in college student. Dr. English's test is a good predictor of academic performance in college freshmen
