Answer #1

Answer: B. experimenter expectancy effects or demand characterristics played a role in the results.

Explanation:

Expectancy effect or demand characteristics: Generally, experimenter will have some expectations on experiment. Those expectations will impact him while taking results. So that he watches whether he is right or not rather than watching what is happening. Hence he will fail to take accurate results.

Switching replication with treatment removal: Imagine A and B are two groups in experiment. First time, we will give treatment to group A and we will not give treatment to group B and take results.

Second time we will not give treatment to group A and we will give treatment to group B and take results. This process is called switching replication with treatment removal.

In switching replication with treatment removal, both times experimenter is taking the results. Hence expectancy effect will be there. That's why statement B is the correct answer.
