What is the difference between variable resistor and a resistor in electricity? How does a potential divider circuit work and where is it used in real life? Explain the statement: current is not used up as it f
We have kept it here because this was the wording used in the survey, but future studies in this area might opt for more precise wording. 2 It is more correct to say that the average of a standardized variable is always 0, rather than the average of a set of z-scores is always 0....

Test anxiety is a key affective variable that can impede both achievement in general (Cassady & Johnson, 2002; Fonteyne et al., 2017; Hancock, 2001) and mathematics achievement, in particular (Higbee & Thomas, 1999; Ma, 1999). It is defined as a subjective emotional state that includes re...
Orthodox quantum mechanics is silent about point 2, thus not belonging to what is denoted ontic interpretations. Orthodox quantum mechanics has never denied that something “exists” or – so to speak – that there is an “out there”. That was and is a fairy tale still ...
•Both multiple linear and multiple logistic regression can fit a model where one (or more) predictor (independent) variable is categorical with three or more levels. PriSm automatically creates new variables ("dummy variables", one fewer than the number of levels) to use in regression. Options...
Interestingly, this summary doesn’t reflect my own interpretation of what different results might indicate. Rather, if the interference pattern is lost, even without an observer, when there is switch in the photon source midway during the experiment, then this might indicate that there is an ong...
In both cases x cannot be a product of some useful system. Therefore x has its meaning only by theory(=model() )and X(= some concept) relations. Concept_of_a_number is not a Theory_of_numbers, and theory_of_numbers without Concept_of_a_number is an empty model(=model() ...
This chapter is titled ‘What should we use?’ to achieve the educational purpose discussed in Chap. 1, and so the Models of Engaged Learning and Teaching (MELT) are offered for use and explained in detail, emphasising the shared features of...
considerable research efforts have followed up on this possibility through a wide assortment of empirical investigation. Perhaps the most influential study in this regard is Dehaene et al.’s (1993) original findings on the SNARC effect (Spatial-Numerical Association of Response Codes). In brief, ...
