. The treatment intervention, or ________, is given to the treatment group in order to measure its effect.

. The parameters being manipulated by the experimental design are referred to as:

. The group who does not receive the stimuli being tested, and who receives a placebo instead, is called the ___________.

. Which type of experiment is most appropriate when the phenomenon under investigation is hard to identify in real life?

. If something exogenous to the causal relationship under investigation created a situation similar to if an experimental treatment had been put in place, researchers can study it as a ______.

. In a ______, participants are given an activity, exposed to the treatment, and then asked to do the activity to measure the difference.

. In a factorial design, sample sizes must be __________ in order to ensure adequate statistical power.

. The challenge that researchers will overestimate their ability to manage all the elements at work in experimental research is called ____________.

. A double-blind design is an experiment in which both subjects and treatment administrators are unaware of the effect being tested.

. A split-ballot design is a method involving conducting an experiment in real world environments.

. Experiments are particularly valuable for demonstrating causation while removing confounding variables.

. The fundamental problem of causal inference is that we cannot observe a given case in both treated and untreated states.

. Every experiment has the same number of levels, but a varying number of factors.

. Survey experiments have low internal validity but high external validity.

. Experiments pose fewer ethical challenges than observational research.
