#' data_s - Duration of word-final /s/ in English
#'
#' The Duration of word-final /s/ in English data set, data_s, contains data on three different types of word-final /s/ in
#' English, i.e. non-morphemic, plural, and is-clitic /s/. The data is fictional, but closely related to the original data used in a study by Schmitz et al. (2021).
#' A possible question to investigate with this data set is whether the duration of /s/ depends on the type of /s/.
