Enhancing Student Understanding of Color Perception: A Teaching Activity on Intersubjective Color Variations

Abstract

Introductory statistics textbooks rarely discuss the concept of variability for a categorical variable and thus, in this case, do not provide a measure of variability. The impression is thus given that there is no measurement of variability for a categorical variable.A measure of variability depends on the concept of variability. Research has shown that "unalikeability" is a more natural concept than "variation about the mean" for many students. A "coefficient of unalikeablity" can be used to measure this type of variability.Variability in categorical data is different from variability in quantitative data. This paper develops the coefficient of unalikeability as a measure of categorical variability.

Ambienti fisici di apprendimento che favoriscono i processi attentivi: gli effetti dello spazio vuoto, del colore e del design biofilico

“…Dallo studio di Naz e Epps (2004) emerge che il verde ha un effetto calmante, richiama la natura e dona un senso di equilibrio e armonia. Allo stesso modo, il blu incoraggia il pensiero logico e aumenta la concentrazione (Gatzia, Einsporn & Ramsier, 2017).…”

The Impact of Colour on Students’ Perception in Learning Spaces

“…Blue is perceived as intellectual and logical thinking motivator that encourages clear thought, increases focus and because of this it is advised to be used in classrooms or studying spaces. It is a calming color because it reminds us of sea water and sky[15].…”
