文]翻譯句子
"We use paired difference (test) because of blood pressure variation across
subjects."
因為研究對象之間血壓變化的程度，我們使用了「配對差異」(的统計測試方法)。
呢句說話點解?
「配對差異」分析，做法是配對實驗前的測試值和實驗後的測試值，計算兩者的差異，以抵消研究對象之間變化程度可能造成的錯誤。

(參考：In
statistics, a paired difference test is a type of location test that is
used when comparing two sets of measurements to assess whether their
population means differ. A paired difference test uses additional
information about the sample that is not present in an ordinary unpaired
testing situation
In a "paired
difference analysis", we would first subtract the pre-treatment value
from the post-treatment value for each subject, then compare these
differences to zero.)

我地用配對區別，係因為血壓既變化而產生既跨學科。

"We use paired difference because of blood pressure variation across subjects."

“我們使用配對的區別，因為血壓的變化跨科目。”

因為穿過主題的血壓變化,我們使用配對的差別。

我們用一對不同的配件因為血壓變化超越主要的物件。
