Types of Observations in Experiments

The video tutorial explains the difference between quantitative and qualitative observations. Quantitative observations involve numbers and measurements, such as weight or temperature, while qualitative observations describe characteristics like color or texture. The video provides examples of each type and includes exercises to help learners identify whether a given observation is quantitative or qualitative.
