    In statistics, bivariate data means two variables or measurements per observation. For purposes of this section, we will assume both measurements are numeric data. These variables are usually represented by the letters X and Y.

    Example: Sunglasses sales and rainfall

    A company selling sunglasses determined the units per 1000 people and the annual rainfall in 5 cities.

    X = rainfall in inches

    Y = sales of sunglasses per 1000 people. 

    X Y
    10 40
    15 35
    20 25
    30 25
    40 15

    In this example there are two numeric measurements for each of the five cities.
