Exhibit 1-1
A scientist randomly divided a group of 100 lab rats into two groups of 50. One group was fed regular rat
chow while the other was fed the same amount of rat chow with added DDT. Both groups were housed in
the same room with the same environmental conditions. At the end of the experiment, rats were weighed
and the mean difference calculated.
28. Refer to the accompanying narrative. What variable or variables were manipulated by the scientist?
a. DDT only
b. temperature only
c. weight differences only
d. both DDT and weight differences
e. both temperature and weight differences
ANSWER: a
POINTS: 1
REFERENCES: Section 1.5 How does science work?
LEARNING OBJECTIVES: BCA.SES.1.5.3 - Using a suitable example, distinguish between dependent
and independent variables.
KEYWORDS: Bloom's: Apply | Analyze
29. Refer to the accompanying narrative. What dependent variable was measured?
a. DDT
b. temperature
c. weight

30. In order to reduce bias, scientists usually prefer experiments that lead to what kind of results?
a. ambiguous
b. imprecise
c. quantitative

KEYWORDS: Bloom's: Understand
31. Suppose that in an experiment, different results are obtained from a subset than the results obtained
from the whole. What term would best explain this?
a. probability
b. trend
c. variable
d. statistically significant
e. sampling error

32. An experimenter surveyed one-half acre of a desert preserve and found three cactus wren nests.
Assuming that the habitat is fairly uniform, how many nests would he expect to be in the entire 200-acre
preserve?
a. 6
b. 200
c. 600
d. 1200
e. 6000

LEARNING OBJECTIVES: BCA.SES.1.7.3 - When are experimental results said to be statistically
significant?
KEYWORDS: Bloom's: Apply
33. An experimental result that is statistically significant is:
a. likely to occur by chance alone
b. unlikely to occur by chance alone
c. scientifically significant or important
d. the result of an experiment with only one variable
e. influenced by sampling error
