How do you graph a residual plot?
Here are the steps to graph a residual plot: Press [Y=] and deselect stat plots and functions. Press [2nd][Y=][2] to access Stat Plot2 and enter the Xlist you used in your regression. Enter the Ylist by pressing [2nd][STAT] and using the up- and down-arrow keys to scroll to RESID. Press [ENTER] to insert the RESID list.
What is SST in ANOVA?
The "Sum of Squares Total" in ANOVA. The first of these is often denoted SST and called the "total squared deviation (from the average)", because it is also equal to the sum of the squared deviations of all the data values from the grand average. And the second, denoted DFT, is called the total degrees of freedom.
How do you calculate residual equation?
The formula to calculate residual income is: In the above formula, A = Department's net operating income; B = Minimum required return on assets; and. C = Average operating assets of the department. Department's net operating income is the department's revenue minus all expenses for which the department manager is responsible.
How do you calculate residual in statistics?
Residual Variance Calculation. The residual variance is found by taking the sum of the squares and dividing it by (n-2), where "n" is the number of data points on the scatterplot. RV = 607,000,000/(6-2) = 607,000,000/4 = 151,750,000.

The standardized residual can be interpreted as any standard score. The mean of the standardized residual is 0 and the standard deviation is 1. Standardized residuals are calculated for each cell in the design. They are useful in helping to interpret chi-square tables by providing information about which cells contribute to a significant chi ...

data. Suppose you find the distance from each point in the data to the linear model, then square those distances and find the sum. This is called the sum of the squares of the residuals. The Least-Squares Regression Line (LSRL) is the line that minimizes this sum. The equation of the LSRL is . represents explanatory variable (actual data).
