Question
Which one of the following is the most accurate statement about group differences among students?Question 31Select one:A.When we have knowledge about typical group differences, we have a very good idea of how individual students are likely to perform in the classroom.B.We can make fairly accurate predictions about individual students when we know their ethnic background, but not when we know their gender.C.We can make fairly accurate predictions about individual students when we know their gender, but not when we know their ethnic background.D.The average for two groups may be different, but variability within each group keeps us from predicting individual performance.
Solution
The most accurate statement about group differences among students is D. "The average for two groups may be different, but variability within each group keeps us from predicting individual performance."
This is because while there may be observable trends or averages within certain groups, the individual differences and variability within each group are typically significant. This means that knowing which group a student belongs to (such as their gender or ethnic background) does not necessarily allow us to accurately predict their
