WebIt can be checked visually through a scatter plot. The data is said to be homoscedastic if the points lie equally on both sides of the line of best fit. 3. When the data follow a linear relationship, it is said to be linear. If the data points are in the form of a straight line on the scatter plot, then the data satisfies the condition of ... Webto plot and look.”1 In general, scatter plots may reveal a • positive correlation (high values of X associated with high values of Y) • negative correlation (high values of X associated with low values of Y) • no correlation (values of X are not at all predictive of values of Y). These patterns are demonstrated in the figure to the right.
