Final answer:
ANOVA test is used to compare means of three or more groups. The conditions for ANOVA to be performed include normality of populations, random and independent samples, equal standard deviations, categorical factor, and numerical response.
Step-by-step explanation:
ANOVA test is used to determine the existence of a statistically significant difference among several group means. It helps to compare means of three or more groups to see if they are equal or not.
The conditions that need to be satisfied for ANOVA to be performed are: each population is assumed to be normal, all samples are randomly selected and independent, populations have equal standard deviations, factor is a categorical variable, and response is a numerical variable.
