Analysis of Variance (one way anova) Flashcards
A parametric test used to test the significant difference of three or more groups of data to determine if there is any statistically significant differences between them.
Anova
Also known as F ratio or F-Test.
Anova
A method of testing the differences of three or more population means by analyzing
sample variations (e.g variance).
Anova
If you had only two groups to compare, ANOVA would give the same answer as an independent samples t-test.
Anova
It is named after Ronald A. Fisher who first introduced it.
Anova
Examines the effect of 1 independent variable on the dependent variable.
Anova
Done in ANOVA to determine which specific groups are different from each other.
Post hoc test
[2] Variables in Anova
- Dependent
- Independent
Also known as factor.
[variable]
Independent Variable
Is the variable that you manipulate or categorize to observe its effect on the dependent variable.
[variable]
Independent Variable
This variable divides the data into groups.
[variable]
Independent Variable
Is the outcome or response variable that you measure in the experiment. It is expected to change as a result of variations in the independent variable.
[variable]
Dependent Variable
It is usually something you can measure (like scores, weight, height, or time).
