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, <u>Norman gives the same instructions, the same amount of time and uses the same rubric for grading.</u> Since every student is performing under the same external conditions, we can say that Norman is exhibiting standardization in administering the tests.
Answer:
The time of day the subjects do the study
Explanation:
In research, a confounding variable refers to <u>an external variable that is not originally taken into consideration and that it changes the effect and relation between the independent and dependent variable.</u>

In this example, Dr. Grodner is conducting an experiment on age-related changes in memory by making retirees and high school students take a memory task. However, the older adults come to the lab during the day while the younger ones come in the evening after they finish their daily activities. We can see that <u>Dr. Grodner is not taking into consideration the variable of the time of the day the subjects come to the lab and that this could be an influence in how well they perform in the task (since the younger subjects might be more tired during the evening) </u>and therefore this would be a confounding variable that would change the results of his study making it not reliable.
