可以用numpy模块实现：import numpydef cal_mean_std(sum_list_in): # type: (list) -> tuple N = sum_list_in.__len__() narray = numpy.array(sum_list_in) sum = narray.sum() mean = sum / N narray_dev = narray - mean narray_dev = narray_dev ...
assert np.allclose(r1, r2): This assertion tests whether the values of r1 and r2 are close enough (within a certain tolerance) to be considered equal. If the assertion fails, it will raise an error. Python-Numpy Code Editor: Have another way to solve this solution? Contribute your code ...
所以,采用更大sample size对于估计总体均值有帮助: 1.The larger the sample size, the smaller is the standard deviation of x¯. 2.The smaller the standard deviation of x¯, the more closely the possible values of x¯(the possible sample means) cluster around the mean of x¯. 3.The ...

StdDev: Computes the standard deviation, providing a measure of data dispersion. Motivation: The inclusion of these statistical functions directly in themathpackage will offer Go developers robust tools for data analysis and statistical computation, enhancing the language's utility in scientific and finan...
