This means that interval or ratio scales (where units are exactly the same) are used.

The statistic you obtain to determine statistical significance is the F ratio or F statistic.

This is where the statistical procedure gets its name, Repeated Measures ANOVA.

MANOVA (Multiple Analysis of Variance) - The purpose of this statistical technique is to use multiple dependent and independent variables in a doctoral research design.

Data were acquired from the Programme for International Student Assessment from the Organisation for Economic Cooperation and Development.

The total sample included 150 cases randomly selected from 240 schools in Massachusetts and 150 schools in Germany. So I decided to develop a series of tutorial videos to help you run your analysis. A One-Way ANOVA (Analysis of Variance) is a test that allows us to identify differences between THREE OR MORE groups of means, when you have only ONE independent variable.This is what the “One-Way” stands for: The number of independent variables involved.For example, consider the following hypothetical experiment on age differences in memory for words and pictures.Sixteen 8-year-old children and 16 12-year-old children were shown a set of stimuli and later given a test to see how well they could recognize the stimuli that had been presented.It can reject the null or find differences among groups - if indeed they exist.The assumptions of homogeneity of variance, equal group sizes and normal distribution of scores should be adhered to - just as the t-test should meet these assumptions.The t-test is very handy when you have two groups to statistically compare. Analysis of Variance or ANOVA is the statistical technique that is analogous to the t-test.The ANOVA is an inferential statistic, a parametric statistic and is very powerful.The descriptive statistics may be presented numerically, graphically, or both.The results of the analysis of variance should be discussed with reference to a graph of the group means. Describe the relevant outcomes and back up any claims with the results of statistical tests.
