Document Summary
11. 33905: refer to the histogram of shell lengths (in cm) for the captured sea turtles. Iqr = q3 q1 = 64. 6 - 49. 5 = 15. 1: refer to the boxplot of shell lengths (in cm) for the captured sea turtles. The shape is symmetrical, with the median (center) in the middle of the box and the tails of approximately equal length. The spread is relatively large, as the length of the tails are signi cantly longer than the length of the box. There are no data points plotted individually (which would signify outliers). # scale function standardizes data to nd how many sd an. # observation is away from the mean zscore_aslemand_length
