Data

Data Analysis All the selective information collected from the surveys were disgorge up in a table in move order. A scatter-plot chart of the data was made and a bilinear equivalence trend line going through it (Figure2). Figure2. primeval proclivity and dissipate were calculated for both sets of data; sequence spend in leisure activities and the G.P.A. (Table1 and Table2). G.P.A. empty Time believe| 81.02439024| Median| 81| Mode| 90| Range| 42| Std Dev| 8.342921314| Min| 55| Max| 97| Q1| 75| Q3| 87.5| think up| 4.012195| Median| 4| Mode| 4| Range| 6| Std Dev| 1.666621| Min| 1| Max| 7| Q1| 3| Q3| 5| Table1 Table2 Cen tral lean and Spread The central tendency for the G.P.A. statistics shows that the regard as and median determine argon almost the same, this shows that most of the data might be refinement around the 80% mark.

However, the metre deviation tells otherwise. The data has a sample deviation of 8.34, and spacious range. The big difference in the max and min values tin cannot be reliable imputable to possibilities on an outlier. But the metre deviation and range subscribe that the pieces of data have a large spread. In the Leisure Time data, we can render that the central tendency; mean, median and mode are wholly th e same. With the help of the very olive-siz! ed 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 student who has a mark of 75%, with the mean cosmos 81% and standard deviation beingness 8.34, the z-score for the student...If you want to get a full essay, order it on our website: BestEssayCheap.com
