Answer to Question 1

Measured variables involve pre-existing characteristics of participants. As such, you can't randomly assign participants to categories because you aren't manipulating the variable. Without random assignment, you don't have a true experiment.

Answer to Question 2

(a) Single-case research provides a wealth of detail, much more than for a group design, where in depth information would be too much to evaluate.
(b) Single-case research is also good for studying rare phenomena.
(c) Single-case research can be used for creating and testing research hypotheses.
(d) Single-case research is useful for studying clinical interventions on single people whose specific symptoms are unique.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
