What is ANOVA?
Analysis of Variance (ANOVA) is a statistical method used to test differences between two or more means by comparing the variance between the groups to the variance within the groups. One-way ANOVA is used when comparing means of three or more independent groups to determine if at least one group mean is significantly different from the others.
How to Perform One-Way ANOVA Analysis
Step 1: Prepare your data by organizing it into separate groups. Each group should contain numerical values representing your measurements or observations.
Step 2: Enter the data for each group in the designated text areas. You can separate values using commas or new lines.
Step 3: If you need to analyze more than three groups, click the “Add Group” button to create additional input fields.
Step 4: Click the “Calculate ANOVA” button to perform the analysis.
Step 5: Review the results table, which includes:
- Sum of Squares (SS) for between and within groups
- Degrees of Freedom (df)
- Mean Square (MS) values
- F-statistic
- p-value
Step 6: Interpret the results based on the p-value: If p < 0.05, there is a statistically significant difference between at least two group means. If p > 0.05, there is no statistically significant difference between the group means.
