Question

Analysis of variance is a statistical method of comparing the _____ of several populations


means


proportions


variances


standard deviations

Answer 1

Answer:

Analysis of Variance (ANOVA) is a statistical method used to test differences between two or more means. It may seem odd that the technique is called "Analysis of Variance" rather than "Analysis of Means." As you will see, the name is appropriate because inferences about means are made by analyzing variance.

Answer 2

Analysis of variance is a statistical method of comparing the means of several populations.

What is a variance?

• Variance is the expected value of the squared variation of a random variable from its mean value, in probability and statistics.
• In other words, variance estimates how far a set of numbers are spread out from their mean value.
• Variance = $(Standard Deviation)^{2}$
