Question

A researcher correlates scores on a test (test 1) with scores on other tests (test 2 and3). The analysis demonstrates that the scores on test 1 correlate highly with scores on test 2 but do not correlate with scores on test 3. This type of analysis is used to determine construct validity. San Antonio Texas has a system in which the names of the top three applicants promotion are submitted to the chef of police who then selects one of the three to bethe new captain. This system uses: the rule of threeWhen the two scores from alternate forms of a test are correlated and found to be similar, the test is said to have form stability. Barnum statements are most associated with: face validity. The extent to which tests or test items sample the content that they are supposed to measure refers most specifically to: content validity Setting your clock 10 minutes fast will effect the validity of the clock.If a test is valid for two groups, but more valid for one than the other it is said to have differential validity.

Answer 1

Answer:

The data points should be many

Explanation:

In order for the experiment to be statistically valid, the number of possible data points should be large. This means that the test should have as many data sets as possible. This makes the test to be statistically significant.
