Q Unit 7 Assessment- Relationships Between Variables • Due Oct 24, 2021 by 11:59pm • Points 75 • Submitting a text entry box or a file upload Instructions In this lesson, you will run a correlation between the 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 Dataset 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). o Graph the scatter plot with a trend line. Does it appear there is a linear relationship? What does this mean? o Calculate the correlation coefficient r using excel. Is this r (value) high compared to +1? Based on the correlation coefficient is the relationship strong? o Use excel to find the regression equation. Identify the slope. What does it tell us in terms of our heart rate data?
