Restricted random assignment - Answer-A method of controlling differences in
participant characteristics between groups in a study by first restricting a sample based
on known participant characteristics, then using a random procedure to assign
participants to each group. Two strategies of restricted random assignment are control
by matching and control by holding constant.
Control by matching - Answer-A type of restricted random assignment in which we
assess or measure the characteristic we want to control, group or categorize
participants based on scores on that measure, and then use a random procedure to
assign participants from each category to a group in the study.
Control by holding constant - Answer-A type of restricted random assignment in which
we limit which participants are included in a sample based on characteristics they
exhibit that may otherwise differ between groups in a study.
Error variance or error - Answer-A numeric measure of the variability in scores that can
be attributed to or is caused by the individual differences of participants in each group
Test Statistic - Answer-A mathematical formula that allows researchers to determine the
extent to which differences observed between groups can be attributed to the
manipulation used to create the different groups.
Experimental group or treatment group - Answer-A condition in an experiment in which
participants are treated or exposed to a manipulation, or level of the independent
variable, that is believed to cause a change in the dependent variable.
Placebo - Answer-An inert substance, surgery, or therapy that resembles a real
treatment but has no real effect.
Experimental manipulation - Answer-The identification of an independent variable and
the creation of two or more groups that constitute the levels of that variable.
Natural manipulation - Answer-The manipulation of a stimulus that can be naturally
changed with little effort.
Stages manipulation - Answer-The manipulation of an independent variable that
requires the participant to be "set up" to experience some stimulus or event.
