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
d. amount of food
e. day length
ANSWER: c

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

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
