Which of the following describes qualitative data?

Taking the mass of an object using a balance.

Measuring the volume of an object by water displacement.

Recording the temperature of a solid as it is warmed.

Noting cloudiness occurs when two solutions are mixed.

It would be the second choice (Measuring the volume of an object by water displacement).

Explanation:

Qualitative is defined as relating to, measuring, or measured by the quality of something rather than its quantity. Therefore the second choice is the best option.

Answer: Option (d) is the correct answer.

Explanation:

A quantitative data is defined as the data which can only be described in numbers or figures.

For example, mass of an object is 50 kg.

This is a quantitative data as mass is represented in figures.

On the other hand, a data which describes the nature of a substance and that can only be described in words as there will be no figures or numerical data then it is known as a qualitative data.

For example, Noting cloudiness occurs when two solutions are mixed is a qualitative data.

Thus, we can conclude that the statement noting cloudiness occurs when two solutions are mixed, describes qualitative data.
