Bug ID: 162416
Summary: tutorial/examples for 2-ways ANOVA
Product: LibreOffice
Version: 24.2.5.2 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: enhancement
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]
Description:
All the documentation I found on how to use LO Calc for ANOVA always refers to
1-way ANOVA (1 factor ANOVA). While Calc has the option for 2 factors, there is
no official guide on how to do that.
Steps to Reproduce:
I chose enhancement but I am not sure, it might be a borderline bug or simply a
matter of lack of documentation. To answer this I should know how to use
2-factor ANOVA in Calc properly.
This is especially relevant because there is more than 1 way of structuring the
data to perform the analysis, therefore it is not enough to read the
documentation referring to 1-way ANOVA and simply "extending" to the case of 2
factors.
Actual Results:
For example, the data could be expected in 'wide' format, such as a table with
one factor as columns and another one as rows, with each cell being a single
observation Think of a table with 'warehouse location' as columns (say 3
columns: London, Paris, Buenos Aires) and sellers as rows (say J. Smith, R.
Gomez, L. Lee), and each cell is the yearly revenue (eg. 3234.55 USD).
Or, the data may be expected in 'long' format, eg only 3 columns (Warehouse
location, Seller, Revenue) where all the combinations are listed below.
What is the structure expected by calc? This is unresolved (at least the
documentation I could find), and therefore the 2-factor ANOVA is kind of
unusable or cumbersome at least.
Expected Results:
This should be well documented, just as the single-factor case is currently
documented. The best way is to include example data so the user can clearly see
how to structure the input.
Reproducible: Always
