To answer this question, we divide the number of people by the area.
# of people = 1,355,935,022
divided by
Area = <span>3,705,405 square miles
= 365.93 people/ square mile</span>
What is the question you are asking tho?
<span>The three essential principles of test construction are listed below:
I. Standardization
II. Reliability
III. Validity
</span>Standardization- To standardize a test means that test is given to a large, representative sample of people, in order to establish the norms that future test takers are compared against (using a normal distribution)
Reliability - This principle requires that a test must produce reliable, consistent results when it is repeated. The reliability of a test can be verified using the test-retest method or the split-half method.
Validity - This refers to the ability of a test to measure what it was designed to measure.
