P-values range from 0 to 1.A Quick Introduction to Minitab Statistical Software P-value P-value is a measure of how likely the sample results are, assuming the null hypothesis is true. ANOVA Table ANOVA table is displayed in session window. The boxplot, normal plot of residuals, residuals versus fits, and residuals versus order graphs are popped-up. The One-way ANOVA table is displayed in the session window. Click OK again to generate the results of the One-way ANOVA. Then Click OK back to previous dialogue box. In the dialogue box, check “Boxplots of data”, “Normal plot of residuals”, “Residuals versus fits” and “Residuals versus order”. Then Click Graphs to select the output graphs of the analysis. In the dialogue box which appears, select “C3 Etch Rate” for Response and “C2 Power Level” for Factor by double clicking the columns on the left. To perform the One-way analysis of variance (ANOVA) for stacked data, click Stat Æ ANOVA Æ One Way. Step 2: Performing Data Analysis Example #1 is a one-factor factorial design. Ex: the data for Power Level 160 to 220 are stored in columns C6 through C9 respectively. In unstacked case, the response values of a given treatment are inputted in a separate column. It is a preferred way because it allows arranging data with the corresponding run order (in column C1) so that the independence assumption can be checked in ANOVA analysis. This type of data input is called the stacked case in Minitab. Levels of the treatment / input factorĬorresponding values of the response variable We input the levels of the treatment in one column (C2) and the corresponding values of the response variable in another column (C3). Then you will see the data of the experiment in the worksheet. You may see a pop-up window with message “a copy of the content of this file will be added to the current project.” Click OK. Step 1: Inputting Data Open the Minitab worksheet file by clicking File Æ Open Worksheet, select the file Example_1_Etching_Process.mtw in your stored directory. He is interested in a particular gas (C2F6) and gap (0.80 cm), and wants to test four levels of RF power: 160W, 180W, 200W, and 220W. An engineer is interested in investigating the relationship between the RF power setting and the etch rate. mpj) - Copy and paste from an Excel spreadsheet.Įxample 1 One-Way ANOVA In many IC manufacturing, a plasma etching process is widely used.
