During a 14-week period, half of the sample is administered the drug and the other half is administered a placebo, and participants' concentration abilities are continually tracked. In the context of this study, if Dr. Taylor uses random assignment, it means that ____.
A) his study will be high in external validity
B) the 100 adults are likely to be representative of the larger population of interest
C) each adult has an equal chance of being administered either the drug or the placebo
D) his research findings are likely to be statistically significant
Random Assignment

External Validity
The extent to which the findings from a study can be generalized to other people, other settings, and other time periods.
