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.

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.

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.
