C3  Understand that there is risk involved with drawing conclusions from experiment data—that when generalizing from experiment data, the observed difference in treatment effects may sometimes be due to variability in the response variable and the random assignment to treatments. C4  Understand that data type distinguishes between questions that involve proportions and those that involve means. C5  Know that different methods are used to draw conclusions based on categorical data and to .
