Suppose that you want to investigate whether students who sit close to the teacher tend to perform better on quizzes than those who sit farther away.
a. Identify the observational/experimental units, explanatory variable, and response variable.
b. Describe how you could perform an experiment to address this research question.
c. Identify an advantage of the experiment. Explain.
d. Identify an advantage of the observational study. Explain.

Solution

a)-The observational units /experimental units are the students.
-Variable is the test score of students who sit close to the teacher and those who don\'t.

-It is quantitative because it has a numerical value.

c) Advatage of experiment :

Experimental research focuses mainly on the relationships between known variables. some advatages are i) Control Over Variables ii) Better Results

d)An advantage of the observational

-Data collected is very accurate in nature and also very reliable.

-Improves precision of the research results.
