One sample t-test

Aim

Calculate The aim of the analysis: N for required N, Power for estimated power and Effect Size for minimal detectable effect size

Input

Effect information

Expected Cohen’a d (δ) Expected Cohe’s d
N Expected sample size

Parameters

Minimal desired power Minimal desired power (1-Beta)
Alpha (Type I rate) Critical alpha (significance level to be used in the analysis)
Tails Wheather the test is two-tailed (two.sided) or one-tailed (greater).

Equivalence Testing

Perform equivalence testing Perform an equivalence test to show that a true effect is small enough to be considered practically negligible
Equivalence limit

Options

Explanatory text Produces some text to help interpreting the results

Sensitivity Analysis

Sensitivity analysis, exploring different plots of possible combinations of parameters, can be carried out like for any other PAMLj sub-modules. Please visit Sensitivity analysis page for more details.

Effect Size Conversion

With this panel is possible to estimate the expected effect size based on observed t-test, taken from empirical studies or other empirical sources.

Convert from t-test

Observed t-test Observed t-test value
N Observed t-test sample size
Cohen’s d Resulting Cohen’s d
