with increasingly fewer scores at the upper end of the scale. Negatively skewed data- is negatively skewed because most of the scores tend to occur toward the upper end of the scale while increasingly fewer scores occur toward the lower end. Standard deviation: number minus the mean‚ squared‚ added together and divided by number of values then take the square root. R=1‚ the numbers fall along a straight line‚ positive slope. / R=-1 fall along a straight line with a negative slope. \ R=0 no linear

Define the variable A7.1 An automatic machine in a manufacturing process is operating properly if the lengths of an important subcomponent are normally distributed‚ with mean µ = 117 cm and standard deviation σ = 2.1 cm. If the machine is operating correctly: Let X = variable length of subcomponent (cm). Then if the machine is operating correctly‚ X ~ N (117‚ 2.12 ) .

Hence‚ Standard Deviation of the Grouped Data = s = 1382.98 A low standard deviation indicates that the data points tend to be very close to the same value (the mean)‚ while high standard deviation indicates that the data are spread out over a large range of values. Co-efficient of Variation: (Std. Dev/Mean) x 100 = (1382.98/3967.17)x 100 = 34.86 % The Co-efficient of Variation tells us that the sample standard deviation is only 34.86% of the
