Question
(15 pts) A researcher who is interested in the behavior of chimps believes that temperature is related to aggression in this species of animal. She goes out to her local zoo during a particular weekend and adjusts the temperature of their climate- controlled habitat to 50-degrees, 70-degrees and 90-degrees Fahrenheit over the course of three days, noting the number of aggressive acts she observes at each temperature level. 6. A) What is the independent variable? B) What is the dependent variable? C) Is the dependent variable discrete or continuous? D) What scale of measurement (nominal, ordinal, interval or ratio) is used to measure the dependent variable? E) What research method is being used (experimental or observational), and why?Explanation / Answer
A. In the present study, the variations in the temperature of the climate controlled environment in the zoo is the independent variable.
B. The number of aggressive acts in the Chimps over the three days of study is the dependent variable.
C. In the study, the dependent variable will be discrete as the researcher is interested in noting the instances, that is the number of times the aggressive response occurs rather than the magnitude or intensity of aggressive behaviour.
D. The dependent variable is studied on a ratio scale in which the data can be recorded in ascending or descending order with the addition of an absolute zero to record no change in behaviour due to the change in the temperature.
E. The researcher is using the experimental method as she is manipulating the Temperature condition (independent variable) in the Chimps’ environment and studying its effect on their behaviour (dependent variable) in order to establish a causal relationship in a controlled setting.
