A researcher is interested to see if driving efficacy self-ratings are related to driving ability. The researcher has a group of 15 participants take a self-efficacy questionnaire and participate in an inner-city driving simulation. At the end of the driving simulation, participants are given a score representing their overall driving ability based on participant’s adherence to traffic signs, speed deviation, and eye tracking data. Use the following data the researcher gathered to complete each step of the assignment instructions. What would be the predicted driving ratings if a participant attained a 16 self-efficacy rating?

Question

A researcher is interested to see if driving efficacy self-ratings are related to driving
ability. The researcher has a group of 15 participants take a self-efficacy questionnaire
and participate in an inner-city driving simulation. At the end of the driving simulation,
participants are given a score representing their overall driving ability based on
participant’s adherence to traffic signs, speed deviation, and eye tracking data. Use the
following data the researcher gathered to complete each step of the assignment
instructions. What would be the predicted driving ratings if a participant attained a 16
self-efficacy rating?
Efficacy Driving Ratings

 Use the SPSS program to calculate the correlation and create a scatterplot
 Provide the appropriate output given from the program
 Describe this relationship (both strength and direction, and in layman’s terms)
 Determine if these variables truly related or could there be a third variable at play
 Calculate the regression equation using SPSS-Include the Regression Test output
 Use that regression equation to calculate a prediction described in each problem.
