(b) What is a typical, or representative, crack depth? (c) Does the display appear to be highly concentrated or spread out? (d) Does the distribution of values appear to be reasonably symmetric? If not, how would you describe the departure from symmetry? (e) Would you describe any observations as being far from the rest of the data (outliers)?
