1. Dotplots arc also useful when comparing two samples. 1 on the same horizontal scale; we see immediately that the averages of the two rows arc about the same, but the third row has less variation than the first row. I selected the third row on purpose to illustrate this point: there may actually have been an improvement in the variance during that period, but i t sccms to have been temporary. 00 .. 00 ... 00 I .. 2. 8. STEM-AND-LEAF DIAGRAMS A variation of the histogram was introduced as a tool in exploratory data analysis by J.

The data have been modilicd to make the arithmetic simpler. Each rod is subjected to two tests: length and strength. Each test classifies the rod as either OK or defective. The data can be arranged in a 2 X 2 tablc: two rows and two columns. A sample of 150 rods gives the results that are shown in tablc 3. I . ” The corresponding probabilities lire called the marginal probabilities. In our example, X , pertains to length and X, pertains to strength. They take the values 0, 1: zero if the test result is OK, and one if the rod is defective.

3) and if X , , A’,, . . are independent random variables with expcctations m , , rn2, . . , respectively, and if Y = a , X , + a,X, + * . 4), we sec that if X is a binomial variable with trials and probability p , then V ( X ) = V ( X , )+ V ( X , ) + . * . 1 1. SAMPLING WITHOUT REPLACEMENT In acceptance sampling by attributes, an inspector draws ii sample of n items from a lot, or batch, of N items and observes the number, X , of defectives in the sample. We have argued until now that the probability of drawing a defective part at any stage of the sampling is a constant, p .
