class eelbrain.test.TTestOneSample(y, match=None, sub=None, data=None, popmean=0, tail=0)

One-sample t-test

Parameters

• y (Var) – Dependent variable.

• match (categorial) – Units within which measurements are related (e.g. ‘subject’ in a within-subject comparison).

• sub (index-array) – Perform the test with a subset of the data.

• data (Dataset) – If a Dataset is specified, all data-objects can be specified as names of Dataset variables.

• popmean (float) – Population mean to test against (default 0).

• tail (0 | 1 | -1) – Which tail of the t-distribution to consider: 0: both (two-tailed, default); 1: upper tail (one-tailed); -1: lower tail (one-tailed).

Variables

• mean (float) – Mean of y.

• t (float) – T-value.

• p (float) – P-value.

• tail (0 | 1 | -1) – Tailedness of the p value.

• df (int) – Degrees of freedom.

• d (float) – Cohen’s d.

• full (FMText) – Full description of the test result.
