Question

1. which of the following is an example of a qualitative observation?

the shirt is green.
the shirt has a mass of 8.0 grams.
the shirt is 22 cm long.
the shirt is ugly.

Explanation:

Qualitative observations describe qualities (non - numerical), while quantitative use numbers. "The shirt is green" describes color (a quality). "8.0 grams" and "22 cm" are numerical (quantitative). "Ugly" is subjective opinion, not a standard qualitative observation (qualitative in science is about observable properties like color, texture, not subjective judgments). So the correct example is "The shirt is green".

Answer:

A. The shirt is green
