Dr.Jones systematically varies the temperature in the laboratory (70,80,and 90 degrees Fahrenheit)while holding other variables constant,and observes that the participants' activity level decreases as the temperature increases.This illustrates ____.
A)a non-causal relationship between temperature and activity level
B)a causal relationship between temperature and activity level
C)no relationship between temperature and activity level
D)a nonsystematic relationship between temperature and activity level

Question

Dr.Jones systematically varies the temperature in the laboratory (70,80,and 90 degrees Fahrenheit)while holding other variables constant,and observes that the participants' activity level decreases as the temperature increases.This illustrates ____.​
A)​a non-causal relationship between temperature and activity level
B)​a causal relationship between temperature and activity level
C)no relationship between temperature and activity level
D)​a nonsystematic relationship between temperature and activity level

Quizplus · Accepted Answer

The scenario presented shows that Dr. Jones is performing an experiment in which they systematically vary the temperature and observe the effect on the dependent variable, activity level. In this case, they find that activity level decreases as temperature increases. This suggests a causal relationship between temperature and activity level, with temperature being the independent variable and activity level being the dependent variable that is affected by changes in temperature. Therefore, B is the correct choice.
