What are 5 qualitative observations?
A qualitative observation involves the use of five sensory organs, sight, smell, taste, touch, and hearing, and their function to examine the attributes. Being subjective in nature, it focuses on the characteristics and qualities of the variables rather than the numerical value.
Are teacher checklists qualitative or quantitative?

What’s a quantitative observation?
Quantitative observation implies an objective collection of data for analysis based on their numerical and statistical attributes. This observation involves the depiction of obtained variables in terms of their quantity. The primary focus is on numbers and values.
Is text based quantitative or qualitative?
| Qualitative Methods | Quantitative Methods |
|---|---|
| Text-based | Number-based |
| More in-depth information on a few cases | Less in-depth but more breadth of information across a large number of cases |
| Unstructured or semi-structured response options | Fixed response options |
| No statistical tests | Statistical tests are used for analysis |
What is difference between qualitative and quantitative observations?
Qualitative observations are made when you use your senses to observe the results. (Sight, smell, touch, taste and hear.) Quantitative observations are made with instruments such as rulers, balances, graduated cylinders, beakers, and thermometers. These results are measurable.
