Another method for finding CVs is to use a critical value calculator, such as the one below. These calculators are handy for finding the answer, but they don’t provide the context for the results. This calculator finds critical values for the sampling distributions of common test statistics. ...

You can learn more about the meaning of this quantity in statistics from the degrees of freedom calculator. Set the significance level, αα. By default, we pre-set it to the most common value, 0.05, but you can adjust it to your needs. The critical value calculator will display your ...
Z Critical Value Calculator Home Math Probability & Statistics Z Critical Value Calculator uses a significance level value and test (left-tailed, right-tailed, two-tailed) to calculate z-critical value for the standard normal distribution N(0,1), or close to normal distribution. The Z ...
计算t-value t-value = (sample_mean - Population_mean) / (sample_std / sqrt(n_samples)) t-value = (x_hat - mu) / (s / sqrt(n)) 假设此时 n < 30, 而且 Population std 也是知道的。 此时也可以计算 z-value, zc, 此时可以当做是正态分布来做。
