6 Μαρ 2020 · One-way ANOVA example As a crop researcher, you want to test the effect of three different fertilizer mixtures on crop yield. You can use a one-way ANOVA to find out if there is a difference in crop yields between the three groups.
21 Μαΐ 2023 · The one-way ANOVA test is also referred to as a single-factor ANOVA test because it compares the means across different groups based on a single common factor. In our example, the factor is the different drugs administered to the groups.

12 Μαρ 2023 · The one-way ANOVA F-test is a statistical test for testing the equality of \(k\) population means from 3 or more groups within one variable or factor. There are many different types of ANOVA; we will …
In statistics, one-way analysis of variance (or one-way ANOVA) is a technique to compare whether two or more samples' means are significantly different (using the F distribution). This analysis of variance technique requires a numeric response variable "Y" and a single explanatory variable "X", hence "one-way". [1]
To implement one-way analysis of variance with a single-factor, independent groups design, a researcher takes the following steps: Specify a mathematical model to describe the causal factors that affect the dependent variable.
