Python3使用numpy求均值、方差、标準差

        代碼

import numpy as np

# 使用numpy求均值、方差、标準差
def tc03():
    data = [10.1, 10.0, 10.2, 9.8, 9.9]
    mean = np.mean(data)
    var = np.var(data)
    std_var = np.std(data)
    print("均值：\t", mean)
    print("方差：\t", var)
    print("标準差：\t", std_var)


# 程式入口
if __name__ == '__main__':
    tc03()
           

        輸出

均值：	 10.0
方差：	 0.019999999999999858
标準差：	 0.141421356237309
