平均值与标准差

  • 求平均值=AVERAGE(A0:A9)
  • 求标准差=STDEV.S()(旧版STDEV)和=STDEV.P()(旧版STDEVP
    • STDEV.S:只有部分采样数据,公式为
    • STDEV.P:全部数据(represents the entire population)

STDEV assumes that its arguments are a sample of the population. If your data represents the entire population, then compute the standard deviation using STDEVP
