compare_effect_sizes function

Compare effect sizes

Compares effect sizes See p. 156 of Borenstein et al. (2009, ISBN: 978-0-470-05724-7).

compare_effect_sizes(
  effect_sizes = NULL,
  effect_size_variances = NULL,
  round_stats = TRUE,
  round_p = 3,
  round_se = 2,
  round_z = 2,
  pretty_round_p_value = TRUE
)

Arguments

• effect_sizes: a vector of estimated effect sizes
• effect_size_variances: a vector of variances of the effect sizes
• round_stats: logical. Should the statistics be rounded? (default = TRUE)
• round_p: number of decimal places to which to round p-values (default = 3)
• round_se: number of decimal places to which to round the standard errors of the difference (default = 2)
• round_z: number of decimal places to which to round the z-statistic (default = 2)
• pretty_round_p_value: logical. Should the p-values be rounded in a pretty format (i.e., lower threshold: "<.001"). By default, pretty_round_p_value = TRUE.

Examples

compare_effect_sizes(
effect_sizes = c(0.6111, 0.3241, 0.5),
effect_size_variances = c(.0029, 0.0033, 0.01))
