Document Summary
Median : 34. 00 median : 9. 000 median :13. 00 median : 6. 000. Mean : 43. 52 mean : 8. 407 mean :12. 95 mean : 6. 194. Median :20. 00 median :60. 75 median :34. 00 median :150. 0. Mean :20. 56 mean :58. 62 mean :35. 66 mean :182. 9. Skewed right mean is greater than median: mean and median of weight. Skewed right mean is greater than median: 5 number summary, iqr, range of age. [1] 8 177: 5 number summary, iqr, range of weight. [1] 26 514: standard deviation of weight and age. [1] 121. 8012: boxplots of weight and sex. More spread in the weight of male bears than that of females. Iqr is smaller with females as well, but medians are about the same. For males, skewed right, while females are approx. symmetric: boxplot of age and sex. More variation within the first and second quartiles for the females, but the higher values are expressed in the age for males, these both being outliers.
