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).
Use the Scatter Plot function in the Insert Charts section of Excel to create a scatter plot of the X and Y variables.
Add a trendline to the scatter plot.
Use the Data Analysis tools in Excel to find the regression equation.
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?
