Instructions

In this lesson, you will run a correlation between resting and after-exercising heart rates to determine if a linear relationship exists between the two variables and how strong the relationship is.

Steps

1. Open the  Heart Rate Data Set in Excel and identify the X-variable (resting heart rates for all 200 participants) and the Y-variable (after-exercise heart rates for all 200 participants).

2. Use the Scatter Plot function in the Insert Charts section of Excel to create a scatter plot of the X and Y variables.

3. Add a trendline to the scatter plot.

4. Use the Data Analysis tools in Excel to find the regression equation.

5. In a Word document, describe the relationship between the X-variable (resting heart rate)and the Y-variable (after-exercise heart rate).

· Graph the scatter plot with a trend line. Does it appear there is a linear relationship?  What does this mean?

· Calculate the correlation coefficient r using Excel. Is this r (value) high compared to +1?  Based on the correlation coefficient, is the relationship strong?

· Use Excel to find the regression equation. Identify the slope.  What does it tell us in terms of our heart rate data?
