Animal Behavior Lab Exercise 1: General Observation of Behaviors If you have enough observations after 5 minutes, go ahead and move on. Exercise 2: Observing Kinesis Behaviors in Isopods Download the sample spreadsheet from the course website. Graph your data using to within 95% confidence (a bar graph with the sample means and ±2 SEM error bars) Record you group’s means in Mr. Mohn’s class data spreadsheet. Exercise 3: Design Your Own Experiment Choose your own variable to test. List at least 5 variables you will control.

Animal Behavior Lab - Conclusion Your conclusion should include an analysis of the data with reference to your original hypothesis. Do your error bars overlap? YES – the results “fail to disprove the null hypothesis” meaning the difference between the two means is not statistically significant. Any observed difference can be attributed to chance alone. NO – the results “disprove the null hypothesis” meaning the difference between the two means is statistically significant. The observed difference may be evidence in support of an isopod preference. Discuss at least two possible sources of error in the data and describe how the error may have influenced your results.
