In 2013, Sherman et al. conducted a study to examine how different forms of communication (text messaging, vs. video chat vs. telephone conversation) can influence feelings of closeness and bonding among friends. They instructed participants to come into the lab with their best friend, and randomly assigned them to engage in a 5-minute conversation in one of the three modalities (text message, video chat, or phone conversations). After the conversation, they measured feelings of closeness on a scale of 1- 20. Let's imagine that you decided to replicate this study with 45 participants (15 participants in each group). You can find the data in the questions below. + Dataset for the group Data table Text Message Video Chat Phone Conversation 10 12 9 15 8 7 16 10 10 18 7 11 10 UT 8 18 12 16 11 12 17 10 15 00 14 13 10 14 10 15 10 12 10 10 3 1. What is the of between (also known as the of Numerator)? df = 2 df = 3 df = 27 df = 30 2 . What is the of within (also known as the of Demominator)? 3. What is the critical value? (Remember, if you cannot find the exact DF denominator value in the table, you should look for the closest number that is there). 4. Based on the critical value and the obtained value, do you accept or reject the null hypothesis? 5. Based on your answer to the previous question, should we run a post hoc test (don't worry, I won't make you calculate them, I just want to know if we should do a post hoc test in this situation). Yes or No
