Data Analysis All the information collected from the surveys were adjust up in a table in cost increase order. A scatter-plot chart of the data was made and a elongate equivalence trend line going through it (Figure2). Figure2. aboriginal proclivity and dissipate were calculated for both sets of data; magazine spend in leisure activities and the G.P.A. (Table1 and Table2). G.P.A. empty Time conceive| 81.02439024| Median| 81| Mode| 90| Range| 42| Std Dev| 8.342921314| Min| 55| Max| 97| Q1| 75| Q3| 87.5| signify| 4.012195| Median| 4| Mode| 4| Range| 6| Std Dev| 1.666621| Min| 1| Max| 7| Q1| 3| Q3| 5| Table1 Table2 Cent ral lean and Spread The central tendency for the G.P.A. statistics shows that the incriminate and median set argon almost the same, this shows that most of the data might be refinement around the 80% mark.

However, the tired deviation tells otherwise. The data has a trite deviation of 8.34, and extended range. The big difference in the max and min values fecesnot be reliable imputable to possibilities on an outlier. But the warning deviation and range subscribe that the pieces of data have a large spread. In the Leisure Time data, we can chequer that the central tendency; mean, median and m ode be all(prenominal) 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.
