1. A marketing researcher obtains information from a grocery chain store about the number of annual sales of processed vs. fresh vegetables. What is the source for obtaining the information?

a. archival measures refers to records, data collecting, etc.

b. case studies

c. personal surveys

d. systematic observations

2. The same marketing researcher has respondents rate their preference for different soft drinks according to the following 4-point scale: 0 (do not prefer it all), 1 (barely prefer it), 2 (prefer it), 3 (strongly prefer it). What kind of measurement scale is being used?

a. nominal

b. ordinal we’re talking about the degree of preference

c. interval

d. ratio

3. A researcher makes the statement, “Females will perform better than males in a standardized test of verbal knowledge." This statement is best described as a a. sexist bias

b. null hypothesis.

c. research hypothesis

d. established fact.

4. What relates standard deviation, variance, and range? All three are indices of _________.

a. central tendency of measures

b. variability of measures

c. independent variables

d. dependent variables

5. In a positively skewed frequency distribution of obtained measures, the _______ will definitely be smaller than the ________.

a. mean; median b. median; mode c. median; mean d. mode; median

Drawing it out helps.

Don't forget about the age old question of How does social scientific model approach media?

6. What are the sources of experimental confounds?

Don't forget about the age old question of How do habitat diversity and genetic diversity differ?

a. dependent variables.

b. subject variables

c. treatment variables

d. a and c

e. b and c

7. Error variability in a set of measurements typically are associated with: a. changes of the independent variable

b. within-group variability

c. between-group variability

d. a and c

8. When is it not appropriate to use repeated-measures experimental designs? a. It is never inappropriate

b. When there are possible order effects

c. When there are long lasting carry-over effects

d. When there is subject mortality

9. I scored at the genius level, e.g.,upper 0.1 % level, of an IQ test a year ago. In a more recent test I scored at only the upper 20 % level. What is the most likely source of the difference?

a. instrument decay

b. history

c. maturation We also discuss several other topics like What are the limitations of a survey method?

d.statistical regression (toward the mean)
