Definitions Qualitative observations:

descriptions that do not use numbers. (Colors, smells, tastes, textures, or sounds)

Quantitative observations: descriptions that do include numbers. (If you count objects, or measure). Quantitative observations are often made using tools.

Inference : A conclusion based on evidence
