Notes

• Enter one value per line.
• Validation is done as values are entered, and values are sanitised to remove non-numeric and/or redundant characters.
• Pressing Go when editing values initiates the adding of another value.
• Also, clicking on the ✚ icon adds another data entry field.
• Click on the ✘ icon to the right of a value to remove it.
• Statistics are calculated using jsstats.
• Most calculations are rounded up, to two decimal places. However, Sum and Range are not rounded, and may suffer from precision issues.
• The data series can be passed to the page via the url, e.g.:
  index.html?values=10.0,20.3,16.5
  index.html?10.1,20.3,21.5,14.6
  

Future enhancements

• User interface improvements.
• Calculation of additional statistics.
• Allowance for a second data series.
• Support for values using "," as decimal separator.
