#' @description
#' A data set containing the interval-valued responses to 5 different items
#' measuring the perception of lack of information in expository face-to-face
#' lessons obtained with a questionnaire carried out at the University of Oviedo
#' (Spain). Respondents sex is also included.

#' @details
#' An educational innovation project was carried out for improving
#' teaching-learning processes at the University of Oviedo (Spain)
#' for the 2020/2021 academic year. A total of 50 students have been
#' requested to answer an online questionnaire about their perception
#' of lack of information in expository face-to-face lessons by selecting the
#' interval that best represents their level of agreement to the
#' statements proposed in a interval-valued scale bounded between 1 and 7,
#' where 1 means \emph{strongly disagree} and 7 represents the option
#' \emph{strongly agree}.
#' 
#' These are the 5 items used to measure the perception of the 
#' students about the lack of information in expository face-to-face lessons:
#' \enumerate{
#'     \item I receive too little information from my classmates.
#'     \item It is difficult to receive relevant information from my classmates.
#'     \item It is difficult to receive relevant information from the teacher.
#'     \item The amount of information I receive from my classmates is very low.
#'     \item The amount of information I receive from the teacher is very low.
#' }
#' 
#' Moreover, the students have been requested to indicate their sex too.
