Passage #11
Riverwood’s Consulting Scientists & Engineers
wanted to get a better idea of how many and
what type of fish died from the fish kill. They
used a standard sized bucket and collected
samples of dead fish starting: 1) At the dam,
then downstream to 3) the town water pumping
station, and 2) half way between the two. In
addition to counting the number of fish by type
from each sample bucket, they collected the
average weight and length of the fish by type
and location. Their results are in Table 1.

1. Which variable was directly manipulated by the
Consulting Scientists and Engineers?
2. What variable did the scientists attempt to
control?
3. What dependent variable(s) did they watch and
measure?
4. What was calculated from the data that was
watched and measured?
5. Table 1 was organized first by fish type, the by
location. How else could it be organized?
