Investigation Design Diagram for Animal Behavior Projects Title: Sample format: The effect of (independent variable) on (dependent variable) Research Question: Sample format: How will (independent variable) affect (dependent variable)?) Hypothesis: Sample format: I think (independent variable) will affect (dependent variable) because (explain why you expect/predict this relationship between the variables) Independent Variable: “you choose it” variable (i.e. an event, inter-species, intra-species…) Change in independent variable: Number of Observations: Differences of the Independent Variable Number of times observations were made Dependent Variable: “you measure it” variable (what are you measuring/observing?) (i.e. space usage, behavior) Constant Variables: Independent Variable Factors in an experiment that are kept the same Dependent Variable Constant Variables Definition of Terms Independent Variable: (“You choose it” variable) the variable that is chosen by the experimenter to observe. Dependent Variable: (responding variable) the factor or variable that is being observed as a result of naturally changing or natural difference chosen in the independent variable. Control Group: There is no control group in Animal Behavior Investigations. Constant Variable: Factors in an experiment that are kept the same and not allowed to change or vary. Repeated Trials: The number of times that observations were made Hypothesis: A prediction of the relationship of an independent and dependent variable to be observed and recorded in an experiment; it predicts the effect that the changes occurring naturally in the independent variable will have on the dependent variable. Title: A statement describing an experiment. Titles are often written in the form, “The Effect of the Changes in the Independent Variable on the Dependent Variable.” Adapted from Students and Research: Practical Strategies for Science Classrooms and Competitions, 3rd Edition, by Cothron, Giese, & Rezba.
