Question

1. a total of 144 children started the study, but the researchers noted that 12 children quit participating in their assigned activities and did not complete the second administration of the intelligence test. what do we call these subjects? 8. in general, what can be concluded if a study uses random assignment but does not use random sampling? (hint: think of what we talked about at the end of our lectures for chapters 6 and 7!)

Explanation:

1. Subjects who start a study but do not complete it are called drop - outs.
2. Random assignment helps in establishing cause - effect relationships within the sample, but without random sampling, the results may not be generalizable to the larger population.

Answer:

1. Drop - outs
2. The study can establish cause - effect within the sample, but generalizability to the larger population may be limited.
