Answer:
cross-sectional study
Explanation:
Dr. Milano compares the performance of a group of 20-year-olds, a group of 45-year-olds, and a group of 70-year-olds on several tests of fluid intelligence and several tests of crystallized intelligence. Dr. Milano's investigation BEST exemplifies a <u>cross-sectional study</u>. A cross-sectional study is a type of observational study that analyzes data from a population, or a representative subset, at a specific point in time, it involves the use of different set of people who differ in the trait of interest. For example, the effect of age on intelligence level will involve the selection of subjects across the cross-section of ages of interest.
C-sound judgement, integrity, and practical experience.
I think that's the answer.
Answer:
Dependent
Explanation:
In research, we have two different types of variables:
- The independent variable is the one that the researchers can control and that will have an effect on another variable.
- The dependent variable is the one that cannot be control and that is affected by the independent variable. Researchers observe this variable to see how it changes. This is the variable that will be tested or measured.
In this example Professor Nguyen wants to study the impact of mood on reading comprehension. In other words, he's trying to see the effect mood has on reading comprehension. We can see that <u>reading comprehension will be the variable that is being affected and that will also be measured</u> (using a reading comprehension score), therefore this would be considered the dependent variable.
