To calculate the Residual (R):
\[ R = O - E \]
Where:
A residual is a measure used in statistical analyses, particularly in regression analysis, to determine the difference between observed and predicted values of a dependent variable. The residual for each data point is the vertical distance between the point and the regression line; it is positive if the point is above the line and negative if below. Residuals are crucial for diagnosing the fit of a regression model and for identifying outliers or non-linear patterns.
Let's assume the following values:
Using the formula:
\[ R = 15 - 10 = 5 \]
The Residual is 5.
