This paper (falling within the purview of Physics Education Research in particular, and Science general) deals with a very significant issue related to labeling physical quantities along axes coordinates graphing. It has been discovered that traditional norms specification graph drawing are ambiguous. Such totally ignore inherent nature quantity. Furthermore, as result such specification, each ...

The teaching of functions plays a key role in the secondary mathematics curriculum. Electronic technologies afford deepening student understanding of functions by linking multiple representations. Findings from my previous research which investigated the understanding of functions by students in their final two years of secondary school whilst immersed in a graphing calculator learning environm...

Correlation is an important and widely used concept, and it is usually taught through word explanation or graphic description accompaniedwith a numericmeasure if such ameasure exists. In this note, we explore graphing one of the commonly used correlation measures, Kendall’s , in such a way that we display how Kendall’s is calculated and see how Kendall’s is influenced by data features. © 2006 E...

BACKGROUND Severe obesity is an important and distinct weight status classification that is associated with disease risk and is increasing in prevalence among youth. The ability to graphically present population weight status data, ranging from underweight through severe obesity class 3, is novel and applicable to epidemiologic research, intervention studies, case reports, and clinical care. ...
