Question

3 pts A course in computer graphics technology requires that students learn multiview drawing concepts. The instructor believes that a web-based Interactive drawing program will be a more effective learning tool than the traditional method of using supplementary material printed on paper. The experiment will examine 50 students enrolled in the course. Each will be randomly assigned to either the paper-based instruction or the web-based Instruction. The instructor will administer a standardized drawing test before and after the instruction. What are the treatments? Methods of instruction Types of standardized drawing tests. Students in the course Types of multiview drawing concepts.

Answer 1

Let us start with understanding what is treatment.

In an experiment, the factor (also called an independent variable) is an explanatory variable manipulated by the experimenter. Each factor has two or more levels, i.e., different values of the factor. Combinations of factor levels are called treatments. The table below shows independent variables, factors, levels, and treatments for a hypothetical experiment.

Vitamin C 0 mg 250 mg 500 mg 0 mg Treatment 1 Treatment 2 Treatment 3 Vitamin E 400 mg Treatment 4 Treatment 5 Treatment 6

In this hypothetical experiment, the researcher is studying the possible effects of Vitamin C and Vitamin E on health. There are two factors - dosage of Vitamin C and dosage of Vitamin E. The Vitamin C factor has three levels - 0 mg per day, 250 mg per day, and 500 mg per day. The Vitamin E factor has 2 levels - 0 mg per day and 400 mg per day. The experiment has six treatments. Treatment 1 is 0 mg of E and 0 mg of C, Treatment 2 is 0 mg of E and 250 mg of C, and so on.

In this problem, the answer will be the Types of Standardized drawing tests.

The factors will be the Method of instructions whereas level will be the students taking those tests.
