Use Chapter 6 Data Set 1 to compute the Pearson correlation coefficient. Create a scatterplot.
Answer the following question: What is the correlation? Would you predict the correlation to be direct (positive) or indirect (negative)? Why? Also, include your output from Excel and the scatterplot. You may have to convert the spreadsheet to a pdf if the scatterplot is not appearing.
Example Response/Answer:
r=7.98 (Pearson’s correlation coefficient)
A positive value for r is a correlation direct. The scatter plot shows the data points group themselves from the lower-left corner of the graph to the upper-right corner assuming a positive slope.
