In parametric statistical procedures there is a ___ of data
normal distribution
In ___ there is a normal distribution of data
parametric statistical procedures
Any factor that is NOT directly related to the purpose of the study, but may affect the dependent variable. When these factors are not controlled, they exert a confounding influence on the independent variable, that is they contaminate the independent variable in such a way that their separate effects are obscured.
Extraneous Variable/Confounding factor
What is an extraneous variable/confounding factor?
Any factor that is NOT directly related to the purpose of the study, but may affect the dependent variable. When these factors are not controlled, they exert a confounding influence on the independent variable, that is they contaminate the independent variable in such a way that their separate effects are obscured.
