Question

A university conducts a series of surveys in which subjects are drawn from first year social work students and graduating social work students and finds that graduating students demonstrate much higher rates of approval for the university (in terms of whether they think the classes were relevant, the instructors were competent, etc.). The university then claims that more experience with the university leads to higher approval. What source of internal invalidity has the university not considered

Answer 1

Answer:

"Morality " is the correct answer.

Explanation:

• Experimental mortality seems to be a challenge to internal consistency because when the proportion of dropout rates is significant between the reference groups.
• It is much more likely to have happened unless the state of therapy is particularly troublesome, thereby causing a certain portion of the care community to withdraw away.

Such that the institution didn't find this basis of internal illegitimacy or invalidity.

Answer 2

The source of internal invalidity that the university had not considered when it claimed that more experience with the university leads to higher approval was Experimental Mortality.

Experimental mortality or attrition is a source of internal invalidity that describes the loss of participants from a study before its completion. Graduating students have the advantage of staying throughout the experiment, unlike the students who left the university untimely.

According to Babbie, 2014), Internal Invalidity arises when the conclusions drawn from experimental results do not accurately reflect the actual experiment. Internal invalidity means that other factors affect the dependent variable outside the experimental stimulus.

Thus, the source of internal invalidity that the university had not considered was Experimental Mortality.
