Correlation
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 2 psychological experiments looking at the relationship between variables. For these sets of data you will: (1) use the SPSS program to calculate the correlation and create a scatterplot (2) provide the appropriate output given from the program (3) describe this...
