quantitative chapter 13 Flashcards
An antecedent variable is
A variable which appears prior to the experiement which could impact the independent or dependent variable
An intervening variable does this
Sits between an independent and a dependent variable
random sampling ensures
that everyone has an equal chance of getting picked. it is also the first step
experimental research is all about manipulating
the independent variable to get different results
what’s the third step to experimental design?
measuring the dependent variable
what is the last part of an experiemental design?
debriefing
a historical flaw is the threat to experimental validity because
a historical event has changed the sample
testing flaw
sometimes it does not work the way it should
regression of the mean
scores on tests begin to clump towards the mean
attrition
the number of participants who have left the study since it started
“O” in experiemental design is
when a observation of the dependent vaqriable has been made
“X” in experiemental design is
when the researcher has manipulated the independent variable
quasi-experimental designs
like experimental, but lacks randomization
true experimental designs
participants are randomly placed into an experimental condition and the independent variable is actively manipulated
