Document Summary
To find probabilities in stat crunch, you need the mean and standard deviation. Normal curve: mean=0; standard deviation=1: less than, at most, fewer: data to the left of line, greater than, more than: data to the right of line, between: find area between two lines. Percentile=value, cutoff, quantile, quartile: area to the left, number on #-axis, can be negative or positive, to find percentile, modify the number outside parenthesis ((cid:3410)(cid:3047)(cid:3042) (cid:3034)(cid:3032)(cid:3047) (cid:3047) (cid:3046) (cid:3041)(cid:3048)(cid:3040)(cid:3032)(cid:3045))(cid:3040)(cid:3042)(cid:3031)(cid:3033) (cid:3047) (cid:3046) (cid:3041)(cid:3048)(cid:3040)(cid:3032)(cid:3045) (cid:4666).
