Atest contracting firm has agreed to create a three part social studies test intended to measure sixth graders knowledge of geography, government, and history. the test is to be used as a statewide assessment to govern the allocation of staff development funds for elementary teachers. because of the limitations in administrative time, only 15 items are allowed for each of the three content areas. if the test development firm wants to know if its three test subsections are measuring, with suitable consistency, what they are supposed to be measuring, what kind of reliability evidence would be best?

Internal consistency

Explanation:

In discipline such as research and statistics, internal consistency is referred to as or known as typically or usually a measure that is based on correlations in between different variable and items particularly on a same test or maybe on sub-scale on the larger test. It tends to measure whether variables and items that measure same construct do produce the similar scores.

answer; ///i believe that the correct answer is (a) it is the means by which a person earns money;

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
