From Shapiro-Wilk test, as the computed p-value is greater than the significance level alpha=0.05, the caries data was extracted follows a Normal distribution. This is where the concept of ANOVA comes into play. In order to make a confident and reliable decision, we will need evidence to support our approach. Result: We want to compare mean difference between smoker status relate with number of caries. Secondly, set up and interpret a one-way Analysis of Variance (ANOVA) followed by Bonferroni multiple comparisons in Excel using the XLSTAT software. Firstly, checking normality and secondly ANOVA analysis. Materials and Methods: In this paper will explain how to conduct one-way ANOVA using XLSTAT software, an add on of Microsoft Office Excel. The objective in this study is to provide basic guideline how to conduct one-way ANOVA analysis using XLSTAT Excel. This provides the information that is of most use to the researcher. In ANOVA, multiple comparison methods are designed to investigate differences between specific pairs of means. There are two assumption are needed for this analysis such as normality distribution and randomness & independence. Background: The One-Way ANOVA is commonly used to test statistical differences among the means of two or more groups or intervention or change score.
