What are the implications of inferring causality from a correlation?

	a)	Dangerous, as the correlation may be spurious.
	b)	There is no way of inferring the direction of causality from a correlation alone. Other factors must be considered.

Regarding the selection and measurement of the dependant variable, which of the following statements is false?

	a)	A floor effect occurs when participant's scores are too close to the top of the scale.
	b)	A ceiling effect occurs when participant's scores are too close to the top of the scale.
	c)	Floor and ceiling effects can be obtained when a full range of scores on the dependent variable cannot be obtained by manipulation of the independent variable.
