Provide two columns of data that are related and demonstrate the Excel Scatterplot Correlation and Regression methodology. Which is the Independent and Dependent variable?
Solutions
Expert Solution
Following data of two variables: height and weight of 6 persons:
| Serial no. of Persons | Height (in cm) | Weight (in Kg) |
| 1 | 162 | 58 |
| 2 | 165 | 60 |
| 3 | 167 | 65 |
| 4 | 168 | 67 |
| 5 | 170 | 72 |
| 6 | 175 | 75 |
Here height is an independent variable and Weight is a dependent variable.
Now
we add regression line to the scatter plot.
