分散分析(ANOVA)の結果の書き方(英語)

2020年8月15日

ここではANOVAの結果を英語で書く場合の文例を記載します。日本語でどのように書くのかは、こちらを参考にしてください.

一要因のANOVAを使う場合の、英語の文例

こちらと同様、各被験者にA/B二つの条件で実験を行い、各条件の施行後に取ったアンケート結果に差が有るかどうかを調べるために被験者内計画の一要因分散分析を行った状況を想定します。自由度やF値については仮の値なので、適宜数字を入れ替えてください。

有意差がある場合

We conducted a within-subjects ANOVA on the conditions, and the result showed a significant difference between the conditions (F(1,XX)=X.XXX, p=0.021, partial η2=0.0XX). Thus, the proposed condition significantly increased the questionnaire results more than the alternative condition.

有意差がない場合

We conducted a within-subjects ANOVA on the conditions, and the result did not show any significant difference (F(1,XX)=X.XXX, p=0.401, partial η2=0.0XX).

二要因のANOVAを使う場合の、英語の文例

こちらと同様、要因名は、映像要因(あり・なし)および音声要因(あり・なし)と仮に設定します。有意傾向のみの事例は省いています。

全ての要因及び交互作用に有意差がある場合

We conducted a two-factor repeated measures ANOVA on the conditions, and the result showed a significant difference in the video factor (F(1,XX)=X.XXX, p=0.021, partial η2=0.0XX), the audio factor (F(1,XX)=X.XXX, p=0.013, partial η2=0.0XX), and the interaction effects (F(1,XX)=X.XXX, p=0.043, partial η2=0.0XX). The simple main effects showed a significant differences: in the with-video condition (with-audio > without-audio, p < 0.001) and in the with-audio condition (with-video > without-video, p < 0.001).

片方の要因にのみ有意差があり、交互作用には有意差が無かった場合

We conducted a two-factor repeated measures ANOVA on the conditions, and the result showed a significant difference in the video factor (F(1,XX)=X.XXX, p=0.021, partial η2=0.0XX). We did not find any significant differences in the audio factor (F(1,XX)=X.XXX, p=0.515, partial η2=0.0XX), and the interaction effects (F(1,XX)=X.XXX, p=0.233, partial η2=0.0XX).

有意差がない場合

We conducted a two-factor repeated measures ANOVA on the conditions, and the result did not show significant differences in the video factor (F(1,XX)=X.XXX, p=0.621, partial η2=0.0XX), in the audio factor (F(1,XX)=X.XXX, p=0.515, partial η2=0.0XX), and the interaction effects (F(1,XX)=X.XXX, p=0.233, partial η2=0.0XX).

三要因のANOVAを使う条件の例

こちらと同様、要因名は、映像要因(あり・なし)と音声要因(あり・なし),および性別要因に設定します。

全ての要因及び二次の交互作用に有意差がある場合

We conducted a three-factor mixed ANOVA for each scale on video, audio, and gender and identified significant main effects in the video factor (F(1,XX)=X.XXX, p=0.021, partial η2=0.0XX), the audio factor (F(1,XX)=X.XXX, p=0.021, partial η2=0.0XX), the gender factor (F(1,XX)=X.XXX, p=0.015, partial η2=0.0XX), and the two-way interaction effect (F(1,XX)=X.XXX, p=0.021, partial η2=0.0XX52)=0.194, p=.824, partial η2=.007). No significance was found in the simple interaction effect between video and audio (F(1,XX)=X.XXX, p=0.821, partial η2=0.0XX), the simple interaction effect between video and gender (F(1,XX)=X.XXX, p=0.821, partial η2=0.0XX), and the simple interaction effect between audio and gender (F(1,XX)=X.XXX, p=0.821, partial η2=0.0XX). A simple-simple main effect showed a significant difference in the with-video condition with the with-audio condition (female > male, p < 0.001).
