#Line plot on minitab express software#
Different software packages sometimes switch the axes for this plot, but its interpretation remains the same. On the Options tab of the Simple Regression dialog box, specify whether you want to display the confidence interval or the prediction interval around the regression line on the fitted line plot. Statistical software sometimes provides normality tests to complement the visual assessment available in a normal probability plot (we'll revisit normality tests in Lesson 7 ). Section 1.3 Are there normality tests for normal probability plots? To create a QQ-plot(quantile-quantile or normal probability plot), select Graph > Probability Plot, choose "Simple," and move "Price" into the "Graph variables" box. If the data points are plotted on the trend line, then the data is normal. Data is plotted on Normality Plot in Minitab with data points being displayed on the trend line. There are multiple ways of checking normality of data, with the most commonly used being Anderson Darling test. In the Fitted Line Plot below, as the X variable (Temperature) increases, the Y output (Strength) decreases: This Fitted Line Plot is a simple example, and in reality the processes we study are usually quite a bit more complicated.
