F比率的意思、翻譯和例句

是什麼意思

「F比率」通常指的是一種統計學和數據分析中的比率或指標,特別是在回歸分析中,它用來檢驗模型的整體顯著性。F比率是通過比較模型的變異性與誤差變異性來計算的,通常用於ANOVA(方差分析)中。這個比率的值越高,表示模型的解釋能力越強。

  1. A number showing how well a model works.
  2. A way to compare different things in a study.
  3. A calculation that helps to see if results are important.
  4. A measure used in statistics to check if findings are significant.
  5. A ratio that indicates the effectiveness of a statistical model.
  6. A statistic that tests the overall significance of a regression model.
  7. A value used to determine if the variance explained by a model is greater than the variance due to error.
  8. A metric used to assess the relationship between dependent and independent variables in a model.
  9. A ratio derived from the variance explained by a model divided by the variance not explained, used for hypothesis testing.
  10. A statistical ratio that compares the variance due to the model against the variance due to error to assess overall model significance.

1:F-ratio

用法:

在統計學中,F比率是用來比較兩個變異數的比率,通常用於ANOVA分析中,以檢驗不同組之間的均值是否存在顯著差異。當計算F比率時,會分析組內和組間的變異,以確定模型的有效性。

例句 1:

我們使用F比率來檢驗不同治療方法的效果差異。

We used the F-ratio to test the differences in effectiveness between different treatment methods.

例句 2:

這個實驗的F比率顯示出組間差異的顯著性。

The F-ratio from this experiment showed significant differences between groups.

例句 3:

在方差分析中,計算F比率是關鍵步驟。

Calculating the F-ratio is a key step in ANOVA.

2:F-statistic

用法:

F統計量是F比率的另一種表述,通常用於回歸分析中,以評估模型是否顯著優於沒有解釋變數的基準模型。它幫助研究者理解變數之間的關係。

例句及翻譯:

例句 1:

F統計量的結果顯示,這個模型能夠有效解釋變量。

The F-statistic results indicated that this model effectively explains the variance.

例句 2:

當F統計量大於臨界值時,表示模型的顯著性。

When the F-statistic exceeds the critical value, it indicates the significance of the model.

例句 3:

在回歸分析中,F統計量用於檢驗整體模型的有效性。

In regression analysis, the F-statistic is used to test the overall validity of the model.

3:Variance ratio

用法:

方差比率是指兩個或多個樣本的變異數之比,通常用於檢驗樣本之間的差異是否顯著。這個概念在許多統計分析中都非常重要,尤其是在比較不同群體時。

例句及翻譯:

例句 1:

我們計算了兩個樣本的方差比率,以檢查其差異。

We calculated the variance ratio of the two samples to check for differences.

例句 2:

方差比率在統計學中用來評估資料的變異性。

The variance ratio is used in statistics to assess the variability of data.
