Introduction
The analysis of covariance, or ANCOVA, is a general linear model which blends ANOVA and regression. ANCOVA is used to test the effect of one or more factors by controlling for other variables. There are multiple ways to use ANCOVA, each with different interpretations. ANCOVA assumes that the two variables (dependent and independent) are lineal related. The variance in the dependent variable can be explained by the independent variable and the covariate

In this procedure you will use student scores on two tests: Reading Comprehension and Maths Skills Assessment. These scores were obtained from students at an elementary school in the United Kingdom who took part in a study on reading comprehension skills in relation to maths knowledge among secondary schoolyear pupils (Appendix A).

ANCOVA is used to test the effect of one or more factors by controlling for other variables. The independent variable is the factor that is being tested, and it will interact with other variables that could affect it. In this case, we’re interested in whether or not students who are assigned a higher level of math proficiency in high school perform better on their exams than those who received lower scores.
The dependent variable (variable measured) can be any of several types: raw score (the number obtained from an exam), standardized test score (number converted into standard deviation units), GPA etc., but they all have one thing in common: they represent differences between people based on something else like gender, race etc..
There are multiple ways to use ANCOVA, each with different interpretations.
ANCOVA is used to test the effect of one or more factors by controlling for other variables. It assumes that the two variables (dependent and independent) are lineal related, and it does not make any assumptions about how much each variable may change as a result of its treatment.
The ANCOVA model takes into account both fixed effects and random error. Fixed effects refer to those factors which remain constant when we vary one factor at a time; they include levels of race/ethnicity, gender, age groupings based on age ranges at time t (elderly vs young adults), etc… Random errors are uncorrected deviations from our expectations about observations due solely to chance events such as measurement errors in survey data collection procedures or sampling variability among individuals within groups defined by race/ethnicity or gender within populations over time periods measured in years rather than months like census counts can provide us with
ANCOVA assumes that the two variables (dependent and independent) are lineal related.
ANCOVA assumes that the two variables (dependent and independent) are lineal related. The dependent variable is a function of the independent variable, but it does not have to be linear in form. In fact, if all you know about your data is that you have a single continuous variable Y and some other observations with values on Y, then this procedure can be applied directly to those data without any additional assumptions being required (see Figure 1). However, if there are several variables involved in your analysis—for example, if you want to test whether an intervention has an effect on an outcome like blood pressure—then ANCOVA will not work as easily because each individual parameter for each individual participant or subject needs to be estimated separately before combining them into one overall estimate for overall effects on outcomes such as hypertension levels among others (see Figure 2).
The variance in the dependent variable can be explained by the independent variable and the covariate.
The variance in the dependent variable can be explained by the independent variable and the covariate.
The error term is explained by both the independent variable and a covariate. It does not explain any of the variance in your dependent variable, but it does explain part of your error term (the difference between what you predicted would happen and what actually happened).
ANCOVA is a useful statistical tool for controlling for variables when comparing groups on other variables.
ANCOVA is a useful statistical tool for controlling for variables when comparing groups on other variables. It’s used to test the effect of one or more factors by controlling for other variables. The ANCOVA method assumes that the two variables (dependent and independent) are lineal related, meaning that they have a direct linear relationship with each other.
Conclusion
The analysis of covariance, or ANCOVA, is a useful statistical tool for controlling for variables when comparing groups on other variables. It’s often used in health sciences research because it lets researchers compare two groups that differ in some way and see how much each group’s outcome changes with the addition or removal of one factor at a time.
