This variable remains constant throughout the cross-sectional study. If you do some research on the weight and height of 100 students of your university, for example, you will most likely have a dataset containing 100 rows and 3 columns: one for the students ID (could be anonymized or not), one for the weight, and one for the height. These data were collected on 200 high schools students and are scores on various tests, including science, math, reading and social studies (socst).The variable female is a dichotomous variable coded 1 if the student was female and 0 if male..

In studies where the plan is to perform a test of hypothesis comparing the proportion of successes in a dichotomous outcome variable in a single population to a known proportion, the hypotheses of interest are: versus. In statistical research, a variable is defined as an attribute of an object of study. The two outcomes are coded as satisfied and not satisfied, respectively.

A variable is a logical set of attributes. In statistics, a categorical variable (also called qualitative variable) is a variable that can take on one of a limited, and usually fixed, number of possible values, assigning each individual or other unit of observation to a particular group or nominal category on the basis of some qualitative property.
