Transcript: Methods Results Helm, E., Gujar, N., & Walker, M.P., (2010). Sleep Deprivation Impairs the Accurate Recognition of Human Emotions. SLEEP, 33(3), 335-342. Procedures: Participants will be provided with an Actigraph to measure sleep quantity over a one week period. They will be instructed to follow their normal sleep schedules. Participants sleep will averaged across the 7 day period to match them into either a low sleep or high sleep group. Using a single-factor between-group match design subjects will be assigned to one of two sleep conditions: Sleep control (7-8hrs) and sleep deprivation (3-4hrs). Sleep will monitored overnight in a laboratory setting. Subjects will be given 5 positive, 5 negative, and 5 ambiguous written social scenarios. The participant will be instructed to rate how they would feel in the given situation on a 5-pt likert scale assessing the emotions happy, sad, and angry.

Coulombe, J.A., Reid, G.J., Boyle, M.H., & Racine, R., (2009). Sleep Problems, Tiredness, and Psychological Symptoms among Healthy Adolescences. Journal of Pediatric Psychology, 36(1), 25-35. Participants in the sleep deprived group will rate all scenarios more negatively (i.e. They will perceive negative scenarios more negatively, perceive ambiguous scenarios more negatively, and perceive positive scenarios less positively). This will confirm our hypothesis. Discussion and Limitations to our Study Statistical Analysis to be used: Nonparametric References Why is this research important?

Hypothesis: Participants in the sleep deprivation group will rate all written scenarios more negatively than people in the control group. Participants: Will be acquired via local universities. The study will be advertised on each university's research site. Participants will be offered monetary compensation of $50 Participants will be informed of possible sleep deprivation Organizational Behavior and Human Decision Processes, 155, 169-180.

Process of formulating interagency agreement is an excellent way for child abuse protection team to establish common ground on key issues (Goldman, 2003) Why do some agencies engage in effective interagency cooperation when handling child abuse cases while others do not? Research Design Example of failed collaboration: Tragic death of Khyra Ishaq Introduction What does the literature say? Alternative Arguments There are over 3 million reports of child abuse made in the United States each year Interagency Agreements and Coordination When Handling Cases of Child Abuse Data came from cross-sectional study taken from one specific year (1988) Answer bias and systematic error Small case number Faulty dependent variable Breusch/Pagan Test chi2(1) 1.54 Prob > chi2 0.215 Factors that encourage interagency collaboration... Test for heteroscedasticity Allows for sensitive and consistent application of policies related to child abuse, for it ensures all professionals involved effectively communicate and cooperate with one another, as well as understand their respective roles (Hammond, 2001). Alternative Hypothesis (Ha1): Regardless of the clarity of the formal or informal interagency agreement, it is expected that state reporting laws will increase coordination. Alternative Hypothesis (Ha2): Regardless of the clarity of the formal or informal interagency agreement, it is expected that police agencies with written policies regarding the handling of child abuse cases will increase coordination. The importance of continuing this research Future studies should consider: Impact of agency written policies on interagency coordination Using larger, more current datasets Written verse informal interagency agreements Policy implications: time, money, resources Control 2: Presence of policy covering how to handle abuse and neglect cases Variable POLICY: Asks respondents the following: Does your agency have a written policy that specifically covers how to handle child abuse and neglect cases? Yes or no. Conceptualization of the Variables Table 3: Regression Analysis

When and why do we use stem and leaf plots? Mean, Median, Mode...Range Mean-the "average" value of set of numbers within a data set. Ex. 8, 12, 24, 10, 18, 6 (6+8+10+12+18+24)/6 = 13 Median-the middle value in an ordered data set. Ex. 13, 13, 13, 13, 14, 14, 16, 18,21 Median = 14 Mode-the value that appears the most often in a data set. Ex. 8, 12, 12, 15, 19, 19, 19 Mode = 19 Range-the difference between the largest and smallest value. Ex. 13, 13, 13, 13, 14, 14, 16, 18,21 Range = 21-13 = 8 Can you find the mean, median, mode, or range? Can you find the mean, median, mode, or range? Box-and-Whisker Plots Each box-and-whisker plot has 3 features 1) A box containing the "middle half" of the data 2) A line inside the box at the median of the data 3) A line extending from both ends of the box to the lower extreme and upper extreme Data is divided into 4 equal parts called quartiles. Outliers represent data that is numerically distant from the rest of the data. GLUED TO THE TUBE OR HOOKED TO THE BOOKS? United Streaming Clip

Transcript: Gender Number of chapel skips Why do seniors skip chapel? Conclusion We reject the null at an alpha level of .1, but accept at .05 and .01 Therefore results are not robust, so we cannot reject the null and must assume no significant difference "The only reason I skip chapel is for the celebrations with friends that needs extensive time. Whether it means going to the beach, all-you-can-eat Denny's, or laying in the sun with ice cream, chapel-skipping for me is never an academic endeavor, only time to seize the day with joy." By Ashley Kuck and Ashley Schoen Variables Frequency Table Next steps? The End Bar Graph Compare different classes (freshmen vs. sophomores) Compare years (2012 vs. 2013) Compare first semester to second semester Skipping Chapel We wanted to compare number of chapel skips for senior males vs. senior females are males more interested in chapel than females? do chapels cater to one gender better than the other? The Data There is no statistically significant difference between number of males skipping chapel and number of females skipping chapel Hypotheses "Seniors skip chapel because we no longer have to worry about our registration status for next semester." "...Because we get 45 spare minutes to pretend to do the homework we have to turn in to graduate." "...Because we just don't wanna go." Where did the data come from... Test Results Two sample independent means test Ho: µm=µf Males and females skip chapel equally Ha: µm ≠ µf Males and females do not skip chapel equally The Question Minimum skips: 0 Maximum skips: 36 Total males: 312 Total females: 325 Male mean: 8.56 Female mean: 7.88 Significance Received data from chaplain's office Given total number of skips for each student in the senior class of 2012 during the fall semester
