experiment that manipulates only one variable in an “experimental” group and compares the resulting data to the “control” group
controlled experiment
factors that can affect the results of an experiment
variables
group in which no variables have been manipulated; group observed under “normal” conditions
control group
variable in a controlled experiment that is manipulated
independent variable
variable in a controlled experiment that is measured; the responding variable
dependent variable
premise that any observed differences are simply the result of random differences that arise from drawing two samples from the same population
null hypothesis
experiment involving the comparison of data from different sample groups without trying to control all variables involved
