#'Two Independent Groups - Clean Moral Original Study
#'
#'An example of data from a study with a two independent groups design used in Chapter 7 of the book 
#'\emph{Introduction to the New Statistics}.
#'
#'Some researchers believe that moral judgements are based not only on rational considerations but on one's current emotional state.
#'To what extent can recent emotional experiences influence moral judgements?  Schnall et al. (2008) examined this question by manipulating
#'feelings of cleanliness and purity and then observing if this changes how harshly participants judged the morality of others.
#'Participants completed a word scramble task with either neutral words (neutral priming) or words related to
#'cleanliness (cleanliness prime).  All students then completed a set of moral judgements about controversial scenarios
