正態分布（Normal Distribution）是統計學中一種常見的概率分布，也被稱為高斯分布（Gaussian Distribution）。它在自然界和社會科學中的應用非常廣泛，例如在物理學、經濟學、心理學等領域都有重要的應用。

正態分布的操作步驟如下：

1. 確定問題：首先要明確你需要使用正態分布解決的具體問題是什么。例如，你可能需要計算某個變量的概率密度函數、累積分布函數，或者進行假設檢驗等。

2. 確定參數：正態分布有兩個參數，即均值（μ）和標準差（σ）。在開始操作之前，需要明確這兩個參數的具體數值。

3. 計算概率密度函數：如果你需要計算某個特定數值的概率密度，可以使用正態分布的概率密度函數公式。該公式為：
