Indicate whether the statement is true or false.

1. For the following scores, Σ(X + 1)2 = 81. Scores: 1, 3, 0, 1
a. True
b. False
ST
2. The real limit separating two adjacent scores is located at the upper boundary, or at the higher score.
a. True
b. False
UV

3. If a researcher measures two individuals on an ordinal scale, then it is impossible to determine how much difference
exists between the two people.
a. True
b. False
IA

4. In an introductory theater class, the professor records from the number of movies students watched the previous year.
The teacher is measuring a discrete variable.
?_
a. True
b. False

5. A high school gym teacher records how much time each student requires to complete a one-mile run. This is an
AP
example of measuring a continuous variable.
a. True
b. False

6. The participants in a research study are classified as high, medium, or low in self-esteem. This classification involves
PR
measurement on a nominal scale.
a. True
b. False
OV
7. Constructs are external attributes or characteristics that can be directly observed to describe and explain behavior.
a. True
b. False

8. A recent report concluded that college graduates have higher life-satisfaction scores than individuals who do not
ED
receive college degrees. For this study, graduating versus not graduating is an example of a quasi-independent variable.
a. True
b. False

9. A recent report concluded that children with siblings have better social skills than children who grow up as an only
??
child. This is an example of an experimental study.
a. True
b. False

10. For the following scores, Σ(X – 1) = 10. Scores: 1, 3, 7
a. True

chapter 1

b. False

11. For the following scores, Σ(X + 1) = 9. Scores: 1, 3, 0, 1
a. True
b. False
ST
12. An operational definition identifies a set of operations for measuring an external behavior and then uses the resulting
measurement as a definition of a hypothetical construct.
a. True
UV
b. False

13. For statistical purposes, there usually is not much difference between scores from an interval scale and scores from a
ratio scale.
a. True
IA
b. False

14. The first step in computing Σ(X + 1) is to sum the scores.
a. True
?_
b. False

15. Classifying people into two groups on the basis of gender is an example of measurement on an ordinal scale.
AP
a. True
b. False

16. A researcher is interested in the average income for registered voters in the United States. The entire group of
registered voters is an example of a population.
PR
a. True
b. False

17. In an experimental study, individuals in a control condition receive the experimental treatment.
OV
a. True
b. False

18. Recording the number of students who are absent each day at a high school would be an example of measuring a
discrete variable.
a. True
ED
b. False

19. A researcher interested in vocabulary development obtains a sample of three-year-old children to participate in a
research study. The average score for the group of 20 is an example of a parameter.
??
a. True
b. False

20. If a researcher measures two individuals on a nominal scale, it is impossible to determine which individual has the
larger score.
a. True
