💡Key Phrases and Explanations

Each point represents a sample

散布図の基本フレーズ。研究ではサンプルや試行を指すことが多い。

Clusters tightly / more spread out

まとまりが強い

「広がっている」。群間比較やばらつきを表現するのに適する。

Homogeneous expression

均一な発現。研究データで群の性質を説明するときの有用な表現。

Higher variability

より高い変動。群の一貫性やばらつきを評価するときの一般的な語彙。

Overlap indicates shared patterns

重なりは共通のパターンを示す。PCAや多次元データの散布図で頻出する説明。

Outliers—possibly mislabeled samples or technical artifacts

外れ値の原因を推測する研究者らしいフレーズ。単なる外れ値指摘にとどまらず、解釈を加えると説得力が増す。

Describing a Scatter Plot of Sample Groups

This scatter plot compares two experimental groups based on gene expression profiles.

Each point represents a sample, plotted by two expression markers on the axes.

I see that the blue group clusters tightly, while the red group is more spread out.

Exactly. The compact cluster suggests more homogeneous expression within that group.

The red group shows higher variability, with several points extending outward.

So their expression patterns are more heterogeneous?

Correct. Notice also that the two groups overlap in the center.

That overlap indicates some shared expression patterns despite overall differences.

And what about these points far from both clusters?

Those are outliers—possibly mislabeled samples or technical artifacts.

So, the scatter plot highlights group clustering, variability in spread, overlap, and a few outliers.
