You have been told that people from Texas are more politically conservative than other Americans. So when you meet Raoul, who was born and raised in Texas, you assume that he must be very conservative and treat him accordingly. Which lesson from statistics have you failed to remember?
Select one:
a. Be careful making inferences about individuals based on their group membership.
b. Correlations do not equal causation.
c. Sample size matters (avoid the anecdotal.)
d. Theory and measurement matter.

A. Be careful making inferences about individuals based on their group membership.

Explanation:

Raoul might be from Texas and not be politically conservative , that is why one had to bear in mind that important lesson in statistics about being careful on making inferences on individual based on their group membership. A sample is collected to actually come about that statement but since a sample is just a fraction of the population, generalizing this for all member of the population will be statistically wrong.

okay what's the question?
