Answer the following questions in complete, quality, and correct sentences that reflect the question in your answers.
1. Tell the study subject of this experment.
2a. Identify the Manipulated (experimental) variable in this experiment.
2b. Describe the Responding (measured) Variable.
3. What scientific question is this experiment trying to answer? (Format)
4. Develop an appropriate hypothesis for the above question. (If, Then, Because FORMAT)
5. Identify two controlled variables and one uncontrolled variable in this experiment
(Not the MV or RV).
6. Enter the total for each lab station, then total and average all the classes' data below.
Data Table 3 - Wall Seeking vs Edge Seeking Behavior of Mice
Lab Sta Wall 1/2 Wall 3/4 Walls 5/6 Edges 1/2 Edges 3/4 Edges 5/6 1 2 3 4 5 6 7 8 Totals Averages
7. What was the total number of observations each team took?
8. Tell the total number of observations taken by the entire class?
9. Use the AVERAGES from your Data Table to Bar Graph the data from Data Table 1 below
Use two spaces for each corridor bar, with one between each station.
Label both the x and y axis properly and put the AVERAGE occurrences for each corridor on top of the bar for that corridor.

10. Analyze the Data. Use the TOTALS from Data Table One to determine how often the mice preferred to stay in the different corridors of the box?
Use this formula:
Divide the total occurances for each pair of corridors by the total number of observations taken by the class .
Next multiply this number by 100 to get the %)

Do 11 through 13 . ON A SEPARATE SHEET OF PAPER
11. Create a conclusion that:
a. Restates your original question and hypothesis and tells if it was Accepted or Rejected.b. Explains WHY you came to this conclusion and clearly support each statement with data. Use the averages from Data Table and the percentages above to explain clearly and completely. (Be sure to include the High and Low)
c. Describes what you think caused the results you observed in THIS experiment.
d. Summarizes what you learned in this SERIES OF EXPERIMENTS.
e. Tell 2 important safety precautions that need to be followed in this SERIES OF EXPERIMENTS.
12. Tell how reliable this data was and explain why you think this was so.
13. Explain how to increase the validity of this experiment without changing the study subject. (to improve validity -> develop another, similar, experiment that shows a change in the MV actually caused a change in the RV)
