Z分数计算器
逐步计算 z 分数
该计算器将在给定总体的原始值、均值和标准差的情况下，求出 z 分数（标准化分数），并显示计算步骤。
Solution
Your input: find the z-score of $$$x=2$$$ with $$$\mu = \frac{3}{2}$$$ and $$$\sigma = \frac{2}{5}$$$.
Z-score is calculated according to the following formula:
$$$z=\frac{x-\mu}{\sigma}=\frac{2-\frac{3}{2}}{\frac{2}{5}}=\frac{5}{4}$$$.
Answer: the z-score is $$$z=\frac{5}{4}=1.25$$$.
