What does ANOVA stand for?

• Analysis of Variables

• Analysis of Vectors

• Analysis of Variance

• Analysis of Values

What is the primary purpose of ANOVA?

• To compare means of two or more groups

• To determine correlation between variables

• To calculate standard deviation

• To find the median of a dataset

Which type of ANOVA is used for one independent variable?

• One-way ANOVA

• Two-way ANOVA

• Repeated Measures ANOVA

• Nested ANOVA

What is a key assumption of ANOVA tests?

• Data must be normally distributed

• Data must be ordinal

• Data must be skewed

• Data must be categorical

What does a significant F-statistic indicate in ANOVA?

• There is no variation in the data

• The sample size is too small

• At least two group means are different

• All group means are equal

In a two-way ANOVA, how many independent variables are analyzed?

• One

• Four

• Two

• Three

What is the null hypothesis in a one-way ANOVA?

• The means of the groups are equal

• The means of the groups are different

• The sample sizes are unequal

• There is no correlation

What is a limitation of one-way ANOVA?

• It cannot identify which groups differ

• It assumes all groups have different variances

• It requires more than two groups

• It can only be used with categorical data

What is meant by 'replication' in ANOVA?

• Collecting data from a single source

• Using different statistical methods

• Testing only one group

• Duplicating tests with multiple groups

What is the formula for calculating the F-statistic in ANOVA?

• F = MST/MSE

• F = MSE/MST

• F = MST + MSE

• F = MST - MSE
