TTest Command
From GeoGebra Manual
- TTest[<List of Sample Data>,<Hypothesized Mean>,<Tail>]
- Performs a one sample T test of a population mean using the given list of sample data. Hypothesized Mean is the population mean assumed in the null hypothesis. Tail has possible values "<", ">" , "≠". These specify the alternative hypothesis as follows.
- "<" = population mean < Hypothesized Mean
- ">" = population mean > Hypothesized Mean
- "≠" = population mean ≠ Hypothesized Mean
- Results are returned in list form as {P value, T test statistic}.
- TTest[<Sample Mean>,<Sample Standard Deviation>,<Sample Size>,<Hypothesized Mean>,<Tail>]
- Performs a one sample T test of a population mean using the given sample statistics. Hypothesized Mean and Tail are defined as above. Results are returned in list form as {P value, T test statistic}.
