People like to quantify things to make them easier to understand. The problem is while numbers make things seem more definitive, many times they are just as subjective.
If you say it’s hot that can mean many different things to different people. If you say it’s 95 degrees Fahrenheit it gives it a more definite understanding of hot.
On the other hand some numbers are so subjective they are almost irrelevant. As an example, I was invited to a small 4th of July gathering yesterday. The people who invited me know I don’t like crowds but they assured me it would be a “4 out of 10 in terms of noise and people”. That seemed doable so imagine my surprise when there were 60 people and lots of noise. It ends up that to them, this was a small gathering while to me, it’s a huge crowd.
People like to say statistics don’t lie but statisticians do but the reality is it’s all dependent upon your expectations. If you expect 10 people 60 is a lot. If you expect 500, 60 is a few.
Make sure your starting with the same baseline as others and you will be less surprised by what by what happens.
Have a great day!
