Textbook Question
Chapter 1, Problem 15SQ
In one survey, fifteen randomly selected students were found to be taller than 6 feet. This data led to the conclusion that the average height of a student is greater than 6 feet. This is an example of __________.
- a. experimental error
- b. sampling error
- c. a subjective opinion
- d. experimental bias

Students have asked these similar questions
a) Does the data support your hypothesis?
b) How could you improve this experiment? Consider the other factors you could have / should have controlled in this experiment.
Ideally, an experimental group differs from a control group (a) only with respect to the hypothesis being tested (b) because its subjects are more reliable (c) in that it is less subject to bias (d) in that it is less vulnerable to sampling error (e) only with respect to the variable being studied
