EPPP Practice Exam questions with correct answers

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 "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
