software is utilized; in the other section, it is not. All students are given the same final examination at the end of the semester. Does this represent a designed experiment? Explain in detail.
An experiment involves several characteristics:
1) random assignment to groups
2) active manipulation of the independent variable
3) control of other variables that could influence the dependent variable.
(Remember, we manipulate the independent variable (IV) to measure its effect on the dependent variable (DV) in an experiment).
This design meets all of the requirements of an experiment.
Specifically, the students are randomly assigned to the classes. The advantage of this is that it avoids any differences that ...
