    stats.controlMS;          // => control input converted to ms
    stats.experimentMS;       // => experiment input converted to ms
    stats.controlSortedMS;    // => control input sorted + converted to ms
    stats.experimentSortedMS; // => experiment input sorted + converted to ms
    stats.sampleCount;        // => {control: 10, experiment: 10}
    stats.range;              // => { min: 959, max: 2112 }

    stats.confidenceInterval; // => {min: -46, max: 120, isSig: false}
