What is a control variable in experimental research? It keeps confounding variables to a minimum.
What are the groups in experimental research? Control group and experimental group.
What is random assignment? They are groups chosen by random from the sample. They reduce confounding variables.
What is population and sample in research? The population is everyone that can be part of the research, while the sample is a smaller portion in the experiment that represents the population.
What is generalization? It is the sample being applied to the population.
What is a single blind study? The subjects don't know what group they are in.
What is a double blind study? The researcher and participates don't know which people are in which groups.
What is a correlational study? It measures the strength of the relationship between two variables.
Correlation DOES NOT prove causation So no cause and effect :)
What is positive correlation? When both variables are increasing or decreasing.
What is negative correlation? When the variables are opposites.
What is random sampling? Taking a random survey from the population.
