This assignment will examine your ability to analyze the relationship between two variables, create an equation for predicting one variable from the other, and to critique the results of the data.
You will be given the data for 3
psychological experiments looking at the relationship between variables.
For these sets of data you will:
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 laymans 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.
