Answer:
Standardization
Explanation:
Standardization refers to the methods used to gather information from a group or for a study.
It refers to the fact that every group and member of the group receives the same amount of information, time and that there are no differences between the conditions in which the experiment took place among the different groups.
In this case, Norman gives the same instructions, the same amount of time and uses the same rubric for grading. Since every student is performing under the same external conditions, we can say that Norman is exhibiting standardization in administering the tests.
