Question
Explain about computer output for a one-factor ANOVA.
Expert Solution
Step 1
ANOVA:
The ANOVA (analysis of variance) is a test used for comparing the means of several populations.
In one factor ANOVA model, only one factor is studied, that is, only the effect on one factor is studied simultaneously. In this model, there would be one dependent variable and one independent variable (with more than 2 levels).
Assumptions:
- Each of the populations is normally distributed.
- Population variances are equal.
- The observations in the sample from any particular populations or treatments are independent of one another.
- Samples are selected independently.
