1. What sampling method did researchers use to recruit participants? Identify the method and explain what features of the scenario led you to draw that conclusion

Researchers at PCC are interested in knowing if watching psycho-thriller TV shows leads toincreases in feeling fear. They recruit 20 participants by acquiring a list of phone numbers for all PCC students, and randomly generating numbers to contact until researchers reach a sample size of 20.

Once participants are selected, researchers randomly assign half of the participants to watch psycho-thriller shows (i.e., Ted Bundy Tapes, You, True Detective), and half to watch non-scary shows (i.e., Tidying Up and Great British Baking Show).

After watching the shows, researchers measure how fearful participants are using the Hitchcock Fear Scale. This ranges from 1-100, with 1 meaning no fear, and 100 meaning very fearful.
