Line Plots with Fractional Data

Represent fractional observations on a coordinate axis. Switch partitions between halves, fourths, and eighths, add measurements, and calculate combined statistical aggregates.

  • Tick Intervals: The denominator determines the tick spacing. A denominator of 8 means each tick step is exactly 1/8 units.
  • Sum by Grouping: Multiply each unique value by the number of markers (X's) in its column, then add the fractions together to get the total sum.
  • Average (Mean): Divide the total combined sum by the total count (N) of observations.
  • Range: Subtract the smallest fractional value containing an 'X' from the largest value containing an 'X'.
