Biology 110 - Graphing Assignment - Due September 7, 2005 (10 points)
(Please read the Scientific Graphing Background
handout before starting this assignment)
Below are 4 sets of data.
-
Select 1 of the sets and construct a graph illustrating
the data.
-
Use an entire sheet of graph paper (mm or 10 sq/inch paper) for your graph.
-
Follow the 5 points listed for complete graphs on the Graphing Background
sheet.
-
You must determine which variable is the dependent and which is the independent.
The order they are presented to you in the data set is random.
-
Include a short (2-3 sentence) explanation of what the graphed data
shows.
Data Set 1: A class of 38 dedicated biology students were asked which
of the following heights were closest to their own height. The results
are indicated below:

Data Set 2: A series of 5 gallon aquaria with genetically identical
goldfish (clones!) were set up. Each aquarium was then treated with additions
of increasing amounts of carbonated cola. After each beverage
addition survivorship (percentage of goldfish alive after 24 hours) was
determined as shown below:

Data Set 3: A small sub-basement area of Penn State New Ken is sealed
off and 4 mating pairs of cockroaches are introduced along with 4000 pounds
of dog bisquits. The population size is counted (yuck!) every 2 weeks:

Data Set 4: To check the effect on students of the lack of classroom temperature
regulation at Penn State New Ken, body temperatures of students were taken
and averaged in a wide variety of classrooms with these results:
