on the excel a ADD Stress Behavior Deviation Sq Deviation Calculate each "Student Scores" (X - X1 )2 descriptive statistic (1 through 25 Scale) (X - XI) indicated below. Descriptive Statistics Results Count of Raw Scores N = Mean (Average) EX/N = Sum of Squared Deviations [(x - x1)? = Sample Variance (S, ) [(X - X1) /N = Sample Standard Deviation (Sx) VE (X - X1) /N = +1 Standard Deviation "Unit" (SD) -1 Standard Deviation "Unit" (SD) You just organized and summarized the data. Now, make a Input each group Calculate the deviation statement interpeting your +/- 1 SD unit (S,) results. Based on member's "stress and squared deviation the textbook literature of SD (S,), statistically how could you score" above for each score. interpret the result of +/- 1 SD (e.g. what does it mean)?
