How to Use This Calculator
- Enter each observation once; duplicates represent repeated values.
- Confirm the frequency table to build a dot plot manually or in charting software.
- Use the dot representation column as a quick text-based visualization.
- Apply the summary statistics to describe data spread.
Formula
Dot plots require no special formulas. Each row represents a unique value, and the frequency equals the number of dots stacked vertically at that value.
Frequently Asked Questions
When should I use a dot plot?
Dot plots shine for small to moderate datasets, showing exact values and frequencies without binning.
How do I handle large datasets?
Consider histograms or box plots for thousands of points; dot plots become cluttered beyond about 100 observations.
Can dot plots compare groups?
Yes. Create side-by-side dot plots or overlay values with slight offsets to display group differences.
