Answer to Question 1

B

Answer to Question 2

ANS:
Observer bias occurs when the observer's own perceptions, beliefs and attitudes influence the way he or she observes and interprets the observed behavior. Having more than one observer make independent observations will help detect this bias. Observer effect occurs when people being observed behave differently because they know they are being observed. The observer should be inconspicuous or use a one-way vision screen.
