Plot Power Curve for a One-Sample t-Test

This function creates a ggplot2 power curve for a one-sample t test.

Usage

ggpower_t_one_sample(
  d,
  alpha = 0.05,
  n_range = seq(20, 100, by = 5),
  tails = "two"
)

Arguments

d

Numeric. The effect size (d).

alpha

Numeric. The significance level (default 0.05).

n_range

Numeric vector. A vector of total sample sizes (default is seq(20, 100, by = 5)).

tails

Character. `"two"` or `"one"`.

Value

A ggplot object showing the power curve.

Examples

# Plot power curve for d = 0.5 over sample sizes from 20 to 100
ggpower_t_one_sample(d = 0.5, alpha = 0.05, n_range = seq(20, 100, by = 5))
