Answer:

B. Predictive Validity

Explanation:

Predictive Validity is a type of validity or form of evidence, often used in sociology, psychology or any form of behavioural science test, in which the purpose is to defend the use of a test for predicting other outcomes.

In other words, it is a method of developing validity evidence for employment tests in which a test is given to present employees, then a rating of those employees' job performance that are gathered or obtained independently of the test are used to predict other outcomes.

Predictive validity is however shown when a test correlates well with a measure that has previously been validated.

Hence, in this case, Omar is assessing the Predictive Validity of the test.

Rainbow [258]

Answer:

D. Pleasing climate

Explanation:

One of the reasons that there are many amusement parks in Orlando, Florida is the city's pleasant climate. Amusement parks are usually outside, and good weather is necessary for people to visit them. If it were cold in Orlando, there wouldn't be many visitors, and the parks would close down. The same goes for the population - there would be way fewer visitors if the city had a small population. Interesting local wildlife has nothing to do with amusement parks.

Thus, option D is the correct one.
