The F-ratio is calculated by ____ - correct answer dividing a measure of treatment effects plus error (MSB) by a measure of error only (MSW).
MST is
... [Show More] "mean square total" and is a measure of both_____ and ______. - correct answer treatment effects, error (MSB plus MSW)
MSW stands for "mean square within" and is a pooled measure of variability within each of the treatment groups. It provides an estimate of variability that is due to _____ - correct answer error only
MSB stands for "mean square between" and is a measure of variability between treatment groups. It provides an estimate of variability due to______. - correct answer treatment effects plus error
the ______ is ratio of the variance between groups to the variance within groups. If we consider the variance within groups as due to the random error of individual differences, then the variance between groups must be due to the experimental treatment. The greater the ratio of between group variance to within group variance, the more likely it is that the differences between groups is significant. - correct answer F-statistic
As described by Piaget, the concrete operational stage is characteristic of children between the ages of _____. Children in this stage are capable of ____, which are logical rules for transforming and manipulating information. - correct answer 7 and 11, mental operations
Piaget described transductive (precausal) reasoning as characteristic of the ______. - correct answer preoperational stage
Piaget: A child is exhibiting _______when she assumes that one event caused another only because the two events occurred at about the same time. - correct answer transductive reasoning
Piaget: _____ contributes to the ability to conserve. It is the ability to reverse an action by mentally performing the opposite action. - correct answer Reversibility
Reversibility is part of which stage of Piaget development model? - correct answer concrete operational stage
Piaget: ____ is the ability to mentally compare objects and find differences and similarities between them. - correct answer Transitive inference
Piaget: Transitive inference is a characteristic of the ______ - correct answer concrete operational stage
Piaget: Decentration is characteristic of the ______ - correct answer concrete operational stage
Piaget: _____contributes to the ability to conserve. A child is exhibiting this when he is able to simultaneously focus on more than one aspect of an object or situation. - correct answer decentration
Piaget: objects are treated as though they were people. For example, a child will
smack a 'naughty' chair that has fallen on it. - correct answer Animism:
Piaget: Animism is in what stage - correct answer Preoperational
Piaget: a child's inability to see things from another's point of view. The
classic experiment to illustrate this is often referred to as the 'Swiss Mountain scene' - correct answer Egocentrism:
Piaget: what stage is egocentrism - correct answer preoperational
Piaget: the tendency to pay attention to only one aspect of a situation (usually
the most striking). This characteristic is most dramatically demonstrated in the failure
to conserve. - correct answer Centration: [Show Less]
