Answer to Question 1

ANY REASONABLE ANSWERS OK. EXAMPLES: RECORDING THE DATA ERRONEOUSLY TO MATCH THE DESIRED OUTCOME; TREATING SUBJECTS DIFFERENTLY BASED ON WHICH CONDITION THEY ARE RECEIVING (NOT BEING BLINDED); SUBTLY LETTING THE SUBJECTS KNOW THE DESIRED OUTCOME; EXPERIMENTER EFFECT.

Answer to Question 2

IT IS IMPRACTICAL AND MANY TIMES UNETHICAL TO SUBJECT SOMEONE TO AN EXPERIMENT WITHOUT THEM VOLUNTEERING FOR IT.
