M1 {FuzzyStatTraEOO}

69 trapezoidal fuzzy numbers.

Description

A dataset containing 69 trapezoidal fuzzy numbers. The data correspond to the well-knows questionaire TIMSS-PIRLS2011. This questionnaire was adapted to allow a double-type response, namely, the original Likert and a fuzzy rating scale-based (to simplify, trapezoidal). The questionnaire was conducted on 69 fourth grade students from Colegio San Ignacio (Oviedo-Asturias, Spain). Trapezoidal fuzzy rating responses to the Question M1 "I like mathematics" are collected in this dataset.
