How to fill out correlation and regression line
How to fill out correlation and regression line
01
To fill out a correlation and regression line, follow these steps:
02
Collect your data: Gather a set of paired data, where you have measurements or observations for two variables.
03
Calculate the mean of each variable: Find the average value for both the independent and dependent variables.
04
Calculate the deviation for each data point: Take the difference between each data point and its respective variable mean.
05
Multiply the deviations: Multiply the deviations of both variables for each data point.
06
Calculate the sum of squared deviations: Add up all the squared deviations from step 4.
07
Calculate the correlation coefficient: Divide the sum of squared deviations by the product of the standard deviations of both variables.
08
Interpret the correlation coefficient: The correlation coefficient ranges from -1 to 1. A positive value indicates a positive linear relationship, while a negative value indicates a negative linear relationship.
09
Plot the data points: Create a scatter plot with the independent variable on the x-axis and the dependent variable on the y-axis.
10
Draw the regression line: Use the slope-intercept form (y = mx + b) to draw a line that best fits the data points.
11
Interpret the regression line: The regression line represents the best linear approximation for the relationship between the variables. It can be used to predict the value of the dependent variable for a given value of the independent variable.
