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.S:只有部分采样数据,公式为
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
