2. Description and rationale of statistical test: D. Describe when, why, and how one would use a one-way between-groups ANOVA. What are its benefits? When would a researcher use this test? To answer which kinds of questions? With which types of data? E. Based on the number of IVs and design for the IV, give a specific, descriptive name to the ANOVA as we discussed in class. What is this ANOVA's first, middle, and last name?

Independent Variable (IV):

• Length of the show's episodes, which is categorized into three groups:
  • Short (20-30 minutes)
  • Medium (35-45 minutes)
  • Long (50-60 minutes)
• The IV is manipulated by assigning different groups of participants to watch shows of varying episode lengths. This categorization is fixed and predetermined for the participants.
• Dependent Variable (DV):
  • Duration of the binge-watching session (in minutes) without pausing. This is a continuous variable measured by recording the total time each participant engages in watching the show continuously. The total time can exceed the length of one episode if the participant watches multiple episodes in one sitting.
• The IV (episode length) directly tests the research hypothesis (H1) by examining if different episode lengths lead to variations in the DV (binge-watching duration). The design allows us to determine if the episode length influences how long participants are willing or able to watch continuously, which is central to the research question.
• The null hypothesis (H0) assumes no difference across groups, and by measuring the DV under different conditions set by the IV, we can statistically assess this claim. Should we find significant differences in binge-watching durations across the different episode lengths, we would reject the null hypothesis, supporting the research hypothesis that episode length does indeed impact binge-watching behavior.
• Measurement Methods
  • The measurement of the DV (duration of binge-watching sessions) involves using a stopwatch or a similar time-recording tool to capture the total uninterrupted viewing time from when the participant starts watching until they pause or stop. Each participant's viewing time is recorded in minutes.
  • The IV (episode length) is controlled by providing shows of specific lengths to the participants and ensuring that each participant in a group watches shows only within the designated episode length category.
