One important component to a scatterplot is the direction of the relationship between the two variables. Now positive correlation can further be classified into three categories. When a scatter plot is used to look at a predictive or correlational relationship between variables it is common to add a trend line to the plot showing the mathematically best fit to the data. If the value along the Y axis seem to increase as X axis increases or decreases it could indicate a positive or negative linear relationship. A scatter plot can never prove cause and effect. The more concentrated the dots are along the line the stronger the relationship.
This example compares students achievement motivation and their GPA.
Whether there is a positive or negative association between the variables ie whether the slope is positive or. Positive and negative linear associations from scatter plots Practice. Scatter plots are similar to line graphs in that they use horizontal and vertical axes to. Scatter plot is a graph of two sets of data along the two axes. Scatter plots are used to evaluate the correlation or cause-effect relationship if any between two variables. Perfect Positive Which represents a perfectly straight line.
