Students will represent numerical data on a
scatterplot and then describe the relationship between the variables as
linear or non-linear. If the relationship between the data is
linear, it will have a
positive association, trend or correlation, a
negative association, trend, or correlation, or
no trend or correlation. A
positive association, trend, or correlation in the
linear relationship means that as one set of data increases, so does the other set of data. Also, both sets of data decreasing is also representative of a
positive relationship. In a
negative relationship, as one set of data increases the other set of data must decrease and vice versa. The terms association, trend, correlation, and relationship, can all be used interchangeably.
