  high attendance and high grades tend to occur together.
  high attendance causes high grades.
  smart children often miss school.
  smart children enjoy school.

Question 2

What is one of the reasons that correlations do NOT indicate causation?
 
  Not applicable. Correlations do indicate causation if the correlation is a perfect
  1.0 or +1.0.
  There could be a third variable not being taken into account that can interact
  with the other variables being examined.
  Correlations are unexpected.
  Social scientists do not know why correlations do not indicate causation.
