ANY-maze includes a number of different statistical tests which it can use to analyse your data. As the system already knows certain things about the variables to analyse, such as whether they represent nominal data, whether there are repeated measures etc., it is able to choose an appropriate parametric or non-parametric test for itself – full details are given below.
Section 1
Analysis of nominal data
ANY-maze can perform one-way (but not two-way) analysis of nominal data, such as the first zone entered in a test. To do this it uses the tests shown in table 1. If the result of this analysis is significant (by default, p ≤ 0.05) and you’ve requested post-hoc analysis then the system will employ the tests shown in table 2.
Number of levels of independent variable | Number of levels of dependent variable | Independent samples? | Test |
2 | 2 | Yes | Fisher exact test |
No | Cochran Q* | ||
> 2 | Yes | Contingency table | |
No | Cochran Q | ||
> 2 | 2 | Yes | Contingency table |
No | Cochran Q | ||
> 2 | Yes | Contingency table | |
No | Not supported |

*Strictly speaking this should be analysed using the McNemar test, but the Cochran Q test yields the same answer.
Number of levels of dependent variable | Independent samples? | Ns are equal? | Test |
2 | Yes | – | Not supported |
No | Yes | Multiple comparisons of data subjected to the Cochran Q test (Marascuilo & McSweeney) | |
No | Not supported | ||
> 2 | Yes | – | Not supported |
No | – | Not supported |

Section 2
Analysis of continuous data
ANY-maze can perform one-way parametric or non-parametric analysis of continuous data using the tests shown in table 3. For two-way analysis the tests used are shown in table 4. If the result of this analysis is significant (by default, p ≤ 0.05) and you’ve requested post-hoc analysis then the system will employ the tests shown in table 5.
Parametric data | Number of levels of independent variable | Independent samples? | Test |
Parametric | 2 | Yes | t-test |
No | Paired sample t-test | ||
> 2 | Yes | Between subjects ANOVA | |
No | Within subjects ANOVA | ||
Non-parametric | 2 | Yes | Mann Whitney U |
No | Wilcoxon | ||
> 2 | Yes | Kruskal Wallis | |
No | Friedman |

Parametric data | Independent samples? | Test |
Parametric | Both IVs independent | 2-way between subjects ANOVA |
One IV independent | 2-way between/within ANOVA | |
Neither IV independent | 2-way within subjects ANOVA | |
Non-parametric | Both IVs independent | 2-way Kruskal Wallis |
Either IV not independent | Not supported |
