Custom One-Way ANOVA Calculator
📊 How to Use the One-Way ANOVA Calculator
This guide will walk you through how to use the One-Way ANOVA Calculator with a custom grid input. The calculator allows you to test for significant differences between the means of three or more independent groups.
🧮 Step 1: Select Group and Row Size
- Groups (columns): The number of different groups you are comparing (e.g., Group A, B, C).
- Values per group (rows): How many measurements or data points each group has.
Example: If you have 3 groups with 3 values each, set:
Groups (columns): 3 Rows per group: 3
🧾 Step 2: Click "Generate Input Grid"
This will create an editable table where you can enter the values for each group. Each cell represents a data point.
📝 Step 3: Enter Your Data
Type your numerical values into the table. Each column is a separate group, and each row is a new value for that group.
Example input:
5 6 7 5 6 7 5 6 7
Would be entered like this:
| Group 1 | Group 2 | Group 3 |
|---|---|---|
| 5 | 6 | 7 |
| 5 | 6 | 7 |
| 5 | 6 | 7 |
📈 Step 4: Click "Calculate ANOVA"
The calculator will process your input and display:
- Group Means
- Grand Mean
- SSB (Between Group Variance)
- SSW (Within Group Variance)
- F-Statistic
- P-value (probability that differences occurred by chance)
📊 Bonus: Bar Chart
A bar chart will also appear showing the mean of each group so you can visualize differences.
💡 Tips
- You can increase the number of groups or values to test larger datasets.
- If you see "NaN" or "Error", double-check that all values are entered and valid numbers.
- A low p-value (e.g., < 0.05) suggests a statistically significant difference between groups.
