Ricks, PSYC 200, Spring 2023. Homework 2 Now that you have all of the parts you need to compute s, plug everything into the equation, and then solve the equation. 12. Now interpret the standard deviation in this sample. What does this statistic tell you about the variation in the number of times people in this area get overwhelmed by outhouse stench? 13. Based on the information you have now, would you still live in this rural area? Why or why not? Let's now practice with the computational version of the standard deviation equation! It looks like this: Before you prepare to make calculations, let's practice understanding the formula: 14. Describe in plain English what the following parts of the formula tell you to do. I'll do the rst one for you: a. What does \"2x2\" tell you to do? Square each LndividuaL score, and than sum the squares. b. What does \"Ex\" tell you to do? c. What does \"(2x 2\" tell you to do? Ricks, PSYC 200, Spring 2023, Homework 2 Now compute each part of the raw score standard deviation formula: Neighbor # Times Overwhelmed 15. Ex = by Outhouse Stench 1 12 2 13 3 19 16. Ex = 4 6 5 7 6 15 7 5 17. ( Ex) = 8 8 9 13 10 16 11 11 12 6 18. Plug your calculations into the formula, then solve for s. Show all of your work. Ex2 _ (2x) 2 N ( S = N- 1 -1 (Note that if you get a different result than in 11, you did something wrong for one or both of the equations.) 19. Here, we are computing SD instead of o. Why might someone want to calculate o instead?Ricks, PSYC 200, Spring 2023. Homework 2 20. That was fun, right? Now let's think about how valid this little project was. What are some extraneous variables that may have inuenced your data? That is, what are some other things you should take into account before deciding that these numbers are accurate? Describe two. a. Extraneous variable 1: b. Extraneous variable 2
