Distinguishing Observations from Inferences

The video tutorial explains the difference between observations and inferences. Observations involve gathering information using the five senses and can be qualitative or quantitative. Qualitative observations describe objects, while quantitative observations involve measurements. Inferences are explanations of observations based on past experiences and prior knowledge. Both observations and inferences are valuable in science. The video concludes with a reminder to be kind.
