We use a notation system to refer to these designs. The rules for notation are as follows. Each IV get’s it’s own number. The number of levels in the IV is the number we use for the IV. anova— Analysis of variance and covariance 3 Introduction anova uses least squares to ﬁt the linear models known as ANOVA or ANCOVA (henceforth referred to simply as ANOVA models).

Factorial ANOVA is an umbrella term that covers ANOVA tests with two or more independent categorical variables. (A two-way ANOVA is actually a kind of factorial ANOVA.) Categorical means that the variables are expressed in terms of non-hierarchical categories (like Mountain Dew vs Dr Pepper) rather than using a ranked scale or numerical value.

For the one-way ANOVA, we will only analyze the effect of fertilizer type on crop yield. Sample dataset for ANOVA Die ANOVA (ANalysis Of VAriance – Varianzanalyse) untersucht den Effekt eines oder mehrerer Faktoren (Inner-Subjekt- oder Zwischen-Subjekt-Faktoren) und Interaktionen auf eine abhängige Variable. Die abhängige Variable hat dabei metrisches Skalenniveau. In einem Experiment zur sozialen Kooperation werden vier Faktoren manipuliert: die Anonymität der Personen (vollständige, teilweise, keine), die Anonymität der Entscheidungen (vollständige, teilweise, keine), die Gruppengrösse (3, 4, 5, 6 Personen) sowie die Verfügbarkeit von Sanktionsmöglichkeiten (ja, nein).

Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among means. ANOVA was developed by the statistician Ronald Fisher.ANOVA is based on the law of total variance, where the observed variance in a particular variable is partitioned into components

While the analysis of variance reached fruition in the 20th century, antecedents extend centuries into the past according to Stigler. These include hypothesis testing, the partitioning of sums of squares, experimental techniques and the additive model.
