To provide a baseline for comparison against which the effects of the experimental treatment can be isolated. To replace the need for repeating trials or measuring dependent variables.

To provide a baseline for comparison against which the effects of the experimental treatment can be isolated.

Question 4

Question 5

A strong positive correlation is observed between ice cream sales and drownings during summer months. What does this statistical correlation demonstrate?

Correlation indicates a mathematical association, but does not prove direct cause and effect, often due to a third confounding factor (e.g., warm weather). Drowning incidents cause people to buy more ice cream out of grief. Eating ice cream directly causes muscle cramps that lead to drowning. The data must be fraudulent because negative correlations are mandatory in public health datasets.

Correct Answer:

Correlation indicates a mathematical association, but does not prove direct cause and effect, often due to a third confounding factor (e.g., warm weather).
