Data

Data Analysis All the information collected from the surveys were put up in a elude in ascending order. A scatter-plot chart of the selective information was do and a linear equality trend line passing play through it (Figure2). Figure2. Central tendency and dissipate were calculated for both(prenominal) sets of info; time go across in unfilled activities and the G.P.A. (Table1 and Table2). G.P.A. exculpate Time Mean| 81.02439024| Median| 81| Mode| 90| roam| 42| Std Dev| 8.342921314| Min| 55| Max| 97| Q1| 75| Q3| 87.5| Mean| 4.012195| Median| 4| Mode| 4| get down| 6| Std Dev| 1.666621| Min| 1| Max| 7| Q1| 3| Q3| 5| Table1 Table2 Central sway and Spread The profound tendency for the G.P.A. statistics shows that the blotto and median(prenominal) set argon almost the same, this shows that most of the data might be purgation around the 80% mark.

However, the precedent deviation tells otherwise. The data has a streamer deviation of 8.34, and oversize range. The big difference in the max and min appreciates passelnot be reliable imputable to possibilities on an outlier. But the normal deviation and range support that the pieces of data have a large spread. In the waste Time data, we can picture that the central tendency; mean, median and mode argon all told the same. With the help of the very olive-sized value of standard deviation we can agree that the spread of the data is small and clustered to arouseher. In this case, most of the heap had their leisure time hours at 4 hours. So blush if the central tendency values are close together, the hearty story is always told by the standard deviation. Z-Scores. If we were to find the z-score of a school-age child who has a mark of 75%, with the mean cosmos 81% and standard deviation world 8.34, the z-score for the student...If you want to get a full essay, order it on our website: Orderessay
