23. Nietfeld and Ender (2003) performed a study investigating the relation between the intelligence of student teachers and their efficacy in the classroom. This relation is depicted in the following scatterplot, which shows fictional data that replicate the pattern of performance observed by the researchers. Based on the scatterplot, what kind of relation between intelligence and teaching efficacy did Nietfeld and Ender find? a. positive b. negative c. no relation

Solution

Look at the scatter plot, if points move together forming an upward sloping line, then relation is positive

If points move together forming a downward sloping line, it is negative.

If points are completely random (no linear motion), the it is no relation
