'Considering the speech given by the school principal today, I would conclude that he is not a good public speaker.' Identify the informal fallacy committed in the above argument.

Judging the principal a poor public speaker from a single speech is a hasty generalization.

A general verdict about his speaking ability is drawn from one isolated instance.

One performance is far too small a sample to support a claim about overall skill.

A sound generalization requires enough varied and representative cases.

Leaping to a broad conclusion from scanty evidence is the fallacy of hasty generalization.
