Syntax
GROUPANOVA(<string|integer>, <integer|float >Â ;<float>)
Description
This function is for comparing the means of three or more samples to see if they are significantly different at a certain significance level (usually alpha=0.05).
A JSON object is returned with the calculated F-statistic, the degrees of freedom between the groups, the degrees of freedom with in the groups, the P-value, and a statement if the difference is significant or not.
This is an aggregate function.Â
The function arguments are:
- Sample ID column
- Value column
- Significance level constant (optional)
Example
Example input sheet:
Experiment | Sample_ID | Value |
---|---|---|
A | x | 12 |
A | x | 15 |
A | x | 9 |
A | y | 20 |
A | y | 19 |
A | y | 23 |
A | z | 40 |
A | z | 35 |
A | z | 42 |
Using GROUPBY(#input!Experiment) and
GROUPANOVA(#input!Sample_ID;#input!value;0.05)
Experiment | GROUPANOVA returns |
---|---|
A | {"f-statistic":64.95,"dfbg":2,"dfwg":6,"isSignificant":true} |
