What is the difference between inference and observation?
An observation is what you actually see happening.
An inference is the conclusions you draw from that
To use an analogy;
You may be doing a chemistry experiment and when you put two
substances together, the mixture bubbles and brown gas comes off.
You know that brown gas indicates nitrogen dioxide gas.
The observation would be "Mixture bubbles and brown gas is given
The inference would be "A gas is produced, nitrogen dioxide"
