How do you Use and interpret one-way analysis of variance (ANOVA)? Please provide example(s)
in a research setting, i just want to have an overview on what a one way analysis of variance is and how it is applied in an experiment. eg how do i know to use anova in an experiment?

When we want to compare the mean of two populations, we are using a two-sample t-test. Whereas we want to test more than two mean, we should be used the one-way analysis of variance (ANOVA) (two mean tests also can do by ANOVA). The example of ANOVA tests is given below

Provide an example setting where a Two-Way Analysis of Variance
(ANOVA) would be an appropriate statistical technique for
analysis?
Include the following:
• Research Question or Claim to be Tested
• Description of variables i.e. Categorical (also indicating
nominal, binary/dichotomous, or ordinal and providing levels) or
Quantitative (also indicating discrete or continuous)
o Dependent Variable:
o Independent Variable(s):
• Null and Alternative Hypotheses (using proper notation) Note:
Provide ALL sets of Hypotheses

One-Way ANOVA and Multiple Comparisons
The purpose of one-way analysis of variance is to determine if
any experimental treatment, or population, means, are significantly
different. Multiple comparisons are used to determine which of the
treatment, or population, means are significantly different. We
will study a statistical method for comparing more than two
treatment, or population, means and investigate several multiple
comparison methods to identify treatment differences.

One Way ANOVA (Analysis of
Variance)
A manufacturer of steel wants to test the effect of the method
of manufacture on the tensile strength of a particular type of
steel. Four different methods have been tested and the data shown
in Table 1. (Use Minitab)
Develop the ANOVA table and test the hypothesis that methods
affect the strength of the cement. Use a = 0.05
Use the Tukey’s method with a =0.05 to make
comparisons between pairs of means.
