Document Summary

Variable- a characteristic that can vary in value among subjects in a sample or population (cid:1) (cid:1) (cid:1) (cid:1) Normal variables are variables that have two or more categories, but which do not have an intrinsic order (cid:1) Dichotomous (discrete) variables nominal variables which have only two categories or levels (cid:1) Ordinal variable are variables that have two or more categories just like nominal variables only the categories can also be ordered or ranked (cid:1) (cid:1) (cid:1) Interval variables are variables for which their central characteristic is that they can be measured along a continuum and they have a numerical value. (ex, temperature measured in centigrade) (cid:1) The statistical tool must be appropriate for the variable types. Scale for measurement is a set of categories. Mental health evaluation (well, mild symptom formation, moderate symptom formation, impaired) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Happiness (very happy, pretty happy, not too happy)
