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.

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

exaclty 30 degrees celcius is the answer
