In StefanThoma/ReplicationRelevance: Calculates Relevance for Many Labs Replication Projects

#' Revision protocol dataframe of replication project ML1
#'
#' The original study conducted by Schwarz (1985) investigated the effect of the design of questionnaire-scales (`scalesgroup`)
#' on the information reported by participants (un-intuitively labeled `scales`).
#' Specifically, they randomly assigned $N = 132$ participants either into the low category or the high category group.
#' Participants were asked to rate how many hours of tv they watched per day on a questionnaire.
#' The answer options varied depending on the assigned group.
#' In the low category group six answer categories ranging from *less than 0.5 hours* to *2.5 hours or more* were possible.
#' In the high category group the six answer categories ranged from *less than 2.5 hours* to *4.5 hours or more*.
#' They found that in the high category group significantly more people reported watching more than 2.5 hours of tv per day
#'  compared participants in the the low category group.
#' `
#' The Many Labs 1 project conducted replication attempts in 13 locations and
#'  sample sizes ranged from $N = 71$ to $N = 1261$, totaling $N = 5899$ klein (2014).
#' We used the schwarz study to illustrate LOR.
