ANOVA is the most preferred model in the field of pharmaceuticals and medical research because it helps to find out how effective are the two different types of treatment and how durable they are. In such cases, ANOVA becomes more reliable and effective. It is not reliable when there are more than two samples to be compared. The t-test compares the means between two samples and is also easy to conduct. There are only two tests which can yield the same results – t-test and ANOVA. This is because it is easy to compute manually using simple algebra rather than complex calculations. Though there are different methods like hypothesis testing, partitioning of a sum of squares and others ANOVA is given the first preference these days. The null hypothesis of ANOVA states that all means are equal and the alternative hypothesis states that at least one is different. ANOVA assesses the importance of one or more factors by comparing the variable means at different factor levels. It is used to test the specific differences between the means. It is a statistical method which is used to test the difference between two or more means. Hidden content ANOVA in Minitab What is ANOVAĪNOVA stands for Analysis of Variance.
