Assignment 2: Final Project



Assignment 2: Final ProjectUse the appropriate descriptive statistics from W2: Assignment 2. Assuming that the sample statistics you computed are exactly equivalent to the corresponding population parameters, identify the following:What score on the pretreatment Revised Children's Manifest Anxiety Scale (RCMAS) would correspond to an extremely high score?I will subjectively choose a z-score of 4 to represent extreme values.20.22 + 4(3.74) = 35What score on the pretreatment RCMAS would correspond to an extremely low score?20.22 - 4(3.74) = 5Use SPSS to compute z-scores for Pretreatment RCMAS. Complete the table, indicating the appropriate z-scores corresponding to each of the participants whose score is given.Subject ID Pretreatment RCMAS Z-Score 5 20 ? 10 28? 15 24? 20 28 ? 25 17? Write a brief paragraph interpreting these z-scores.A pretreatment RCMAS of 20 is 0.059 standard deviations below the mean. A pretreatment RCMAS of 28 is 2.080 standard deviations above the mean. A pretreatment RCMAS of 24 is 1.011 standard deviations above the mean. A pretreatment RCMAS of 17 is 0.861 standard deviations below the mean.This is from W2 Assignment 2StatisticsSubjects Age in YearsSubjects RCMAS Pre-treatmentSubjects RCMAS Post-TreatmentNValid999999Missing000Mean11.0620.2211.76Median11.0019.0012.00Mode1018a10aStd.
