Statistical data are often classified according to the number of variables
Univariate data. When we conduct a study that looks at only
we say that we are working with univariate data. Suppose, for example,
that we conducted a survey to estimate the average weight of high
school students. Since we are only working with one variable (weight), we
would be working with univariate data.
Bivariate data. When we conduct a study that examines
the relationship between two variables, we are working with bivariate
data. Suppose we conducted a study to see if there were a relationship
between the height and weight of high school students. Since we are
working with two variables (height and weight), we would be working
with bivariate data
