______ control involves the ability to create situations and randomly assign people to groups; ______ control involves using our heads to anticipate and address all rival plausible explanations.

Mortality refers to a situation in which some individuals drop out of the research before it's completed

Lily is attempting to compare the impact on new drug laws on crime rates in Colorado by comparing it to states that have not adapted similar laws. However, she is finding it hard to find a comparison state. Which internal validity concern is likely the cause?

Compare and contrast how rival plausible explanations are eliminated in traditional laboratory experimentation compared to in quasi-experimentation.

A situation in which you cannot randomly assign people, you should look for ______ to make reasonable guesses about plausibility.

Which of the following people played a significant role in encouraging researchers to reconsider viewing methods in a hierarchical manner?

Quasi-experimentation does not threaten internal validity.

______ may occur if those in the control group perceive the result as adverse and inevitable.

If members in the less desirable group know that they are in the disadvantaged group what internal validity threat may occur?

A local group of dancers know that their ability to learn and replicate dance moves are being compared to the nationally renowned Jabbawockeez. The local group does not put forth their usual effort and does very poorly. What threat to internal validity likely caused this?

The ______ occurs when the treatment or program being evaluated involves goods and/or services considered desirable and where there is a large disparity between groups.

Identify the key differences between manipulative control and analytic control and discuss when each approach should be used.
