Question

A nutritionist conducted an experiment on memory for dreams. She wanted to test whether it really was true that eating cheese before going to bed made you have bad dreams. Over three nights, the nutritionist fed people different foods before bed. One night they had nothing to eat, a second night they had a big plate of cheese, and the third night they had another dairy product, milk, before bed. All people were given all foods at some point over the three nights. The nutritionist measured heart rate during dreams as an index of distress. How should these data be analyzed?

Answer 1

Answer:

All the data collected through this type of experiment should be analyzed upon confrontation of variables combined with the elements exposed to procedure.

Explanation:

In this case, individuals are submitted to ingestion of specific food on a regular basis under the same diet to find out if they could have bad dreams during sleep as an index of distress. They should also be asked to sleep the same amount of hours on a daily rate while the experiment is conducted. The results should be confronted with any particular characteristics that each individual being analyzed could present, such as: age, weight, high/low pressure levels, hours of sleep, medication, regular activities and food habits, among any other possible elements that may be relevant or useful in order to come to a conclusive result.
