Can you identify some examples of variables in your room? Examples in a room might include physical objects such as tables, chairs and people. We need to ask what is it about these things that matters here? It could be the number, size or attractiveness that matters, or something else……
We can see the physical objects but there are other variables that we can’t see eg amount of oxygen, quality of conversation, intensity of light, temperature.
