Description

Includes six pre-registered replication studies testing whether participants feel more powerful if they adopt expansive as opposed to constrictive body postures. In the data set power_pose_unfamiliar, only those participants are included who were unfamiliar with the power pose effect.

Usage

power_pose
power_pose_unfamiliar

Format

A data frame with three variables:

study

Authors of original study

n_high_power

number of participants in high-power condition

n_low_power

number of participants in low-power condition

mean_high_power

mean rating in high-power condition on a 5-point Likert scale

mean_low_power

mean rating in low-power condition on a 5-point Likert scale

sd_high_power

standard deviation of ratings in high-power condition

sd_low_power

standard deviation of ratings in low-power condition

t_value

t-value for two-sample t-test

df

degrees of freedom for two-sample t-test

two_sided_p_value

two-sided p-value of two-sample t-test

one_sided_p_value

one-sided p-value of two-sample t-test

effectSize

Cohen's d, the standardized effect size (high vs. low power)

SE

Standard error of Cohen's d
