Which of the following describes observations that cannot be quantified?

Qualitative observations are descriptions that focus on the characteristics or qualities of an object or phenomenon rather than numerical values. These observations involve attributes that can be subjective, such as colors, textures, shapes, and smells. For instance, stating that a flower is red or a fruit is sour relies on qualitative attributes that cannot be measured numerically.

In contrast, quantitative observations use numbers and measurements to describe an object or phenomenon. Mathematical observations imply a focus on mathematical representations and principles, which also involve numerical quantification. Analytical observations may refer to detailed examinations but do not specifically emphasize the non-numerical aspects of observations.

Qualitative observations are essential in scientific research, especially when exploring aspects that cannot be quantified, as they provide rich, descriptive insights that complement quantitative data.
