2025 biology talkshow: 數據統計分析兵器大解析4:探索關聯與排除干擾--迴歸分析與 ANCOVA

這篇最終章統計學兵器分析探討了兩種進階分析方法：迴歸分析與共變數分析（ANCOVA）。首先解釋迴歸分析如何用來探索兩個連續變數之間的關聯強度與方向，並強調相關不等於因果，透過生物和教育實例說明其應用。接著詳細介紹 ANCOVA，這是一種結合迴歸與 ANOVA 的技術，能讓研究者在比較組別差異時，統計性地排除某個干擾變數（共變數）的影響，從而獲得更公平的比較結果。最後總結強調實驗設計的重要性以及科學家在解讀數據時不應只著眼於 p 值，而必須結合專業判斷來理解結果的實際意義。聽完後可以自主進行線上測驗，檢視學習成效喔~(需要登入gemini) 測驗網址 https://g.co/gemini/share/02f54992dba3 Powered by Firstory Hosting
