(SPSS 25) How To Perform One-Way ANCOVA with interpretation in 20 minutes.

In this video I am going to show how to run one Way ANCOVA and How to test the assumptions and interpret the outcome.
ANCOVA Technique usually use when we want to see the impact of interaction controlling by another scale variable
ANCOVA significantly reduces the error variance compared with ANOVA.
In ANCOVA include one variable is categories (Nominal) such as the three levels of categorical (levels of socioeconomic status) (low, middle, high level) and Two dependent variables (scale or continues such as Read and Write).
Checking the assumptions of ANCOVA:
Test of Normality.
Test of linearity
Test of homogeneity of regression slopes
Test Homogeneity of variance ( Levene's Test)
Running the ANCOVA.
