3. Think About the Process The houses on a certain street are numbered in order with no gaps, starting at 1. The odd-numbered houses are always more expensive than the even-numbered houses. To research the average cost of the houses on this street, you decide take a systematic sample. You choose every eleventh house, starting at house number five.
-
a. What factor should you consider when deciding if your sample is representative of the population?
-
A. Any bias that may be present in the sample
-
B. The names of the people that live in the houses
-
C. The total number of houses on the street
-
D. The time it took to get the sample
-
-
b. Using your answer from the previous step, would the results from your systematic sample be representative of the population?
-
A. Yes, because the pattern in the houses and the interval used introduce a bias in the systematic sample.
-
B. No, because the pattern in the houses and the interval used introduce a bias in the systematic sample.
-
C. No, because the pattern in the houses and the interval used do not introduce any bias in the systematic sample.
-
D. Yes, because the pattern in the houses and the interval used do not introduce any bias in the systematic sample.

4. You are researching the average height of students in your class. You have the students line up in reverse alphabetical order. You take a systematic sample by measuring the height of every ninth student, starting with the fourth. Would the results from your systematic sample be representative of the class?
-
A. No, because there seems to be a relevant pattern in the students that would introduce bias.
-
B. No, because there does not seem to be a relevant pattern in the students that would introduce bias.
-
C. Yes, because there seems to be a relevant pattern in the students that would introduce bias.
-
D. Yes, because there does not seem to be a relevant pattern in the students that would introduce bias.
