| surob | Can someone expain what it means? Why B? |
| arkot90 | it s a measure of absolute dispertion like range so it measures the variability |
| gmilchev | Can someone give more detail? |
| Saxonomy | * Central Tendency would need the mean, or arguably the 50th %ile info. * Relative Position would need to compare a %ile against a reference e.g mean or 50th %ile. * Skewness needs mean against median or vice versa. * Symmetry needs more than 30%/70%, would need 49/51, 45/55, 40/60 and maybe one or two more. Variability is the only answer that you can confidently get from a 30/70 %ile data reference. Hope this makes sense. |
| jejasin | If this were fill in the blank I would've guessed kurtosis... =\ |
| sungryongl | why can't A slo be an answer? mean would be 50th percentile in between 70th and 30th |
