#' Data Set: Power Pose Effect
#'
#' 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 \code{power_pose_unfamiliar}, only those participants are included who were unfamiliar with the power pose effect.
#' @details
#' See Carney, Cuddy, and Yap (2010) for more details.

#' @format A data frame with three variables:
