A standardized procedure is expected to produce washers with very small deviations in their thickness. Suppose that 10 such washers were chosen and their thickness was measured. Below is is the data values and some JMP output: 123, .124, .126, .120, .130, .133, .125, .128, .124, .126 - Thickness Quantiles Summary Statistics 100,0% maximum 0.133 Mean 0.1259 99.5% 0.133 Std Dev 0.0036953 97.5%% 0.133 IN 10 90.0%% 0.1327 75.0% quartile D.1285 50.0%% median D. 1255 25.0%% quartile 0.12375 10.0% 0.1203 2.5% 0.12 0.12 0.125 0.13 0.135 0.5% 0.12 D.0% minimum 0.12
