Document Summary

& 4 non-numerical values presented via calculation of proportion in each category e. g. 61% drink alcohol in the. Each interval has two real limits; one lower real limit and one upper real limit. Bob is at reading scales of measurement often used to measure intervals that are dif cult to assign numerical values to e. g. ranking food preferences ratio scale: interval scale that includes an absolute zero point. Number ratios do demonstrate ratios of magnitude interval scale: interval scale that includes an arbitrary zero point: it does not mean a zero amount of variable being measured. 8. 5 s with a class interval of x=40-49, X=40 and x=49 are apparent limits since they appear to form the lower and upper boundaries of the interval if a continuous variable is being measured basic information x-axis/abscissa y-axis/ordinate y-axis is approx. The endpoints of the interval are known for each scale an intermediate value on one of the scales is given.
