示例1:
this._printStringRow(this._metricNames.map(metricName => {
var samples = validSamples.map(measureValues => measureValues.values[metricName]);
var mean = Statistic.calculateMean(samples);
var cv = Statistic.calculateCoefficientOfVariation(samples, mean);
var formattedMean = ConsoleReporter._formatNum(mean)
// Note: Don't use the unicode character for +- as it might cause
// hickups for consoles...
return NumberWrapper.isNaN(cv) ?
formattedMean :
`${formattedMean}+-${Math.floor(cv)}%`;
