Z 分數計算器
逐步計算 z 分數
此計算器會在給定未標準化值、平均數與母體標準差的情況下，求出 z 分數（標準分數），並顯示計算步驟。
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 $$$z=\frac{5}{4}=1.25$$$.
