Well, it isn’t called “medium”. The median is the number that is right in the middle of the distribution, so if you have the data points: 1, 1, 1, 3, 14, 80, and 141, the median is 3.
The mean/average is what you get if you add all the numbers together and divide that by the number of data points. For the above example the sum is 241, and divided by 7 that is approximately 34.3 .
The mode that @Aussiemandeus mentions is the number that appears the most times, so that is 1.
The cane is there to detect obstacles. They are used to it hitting things, it’s part of their life.
You don’t have to feel bad about it even though it is something you should try to avoid. It’s hard to see that cane when it is poking out in front of the person all the way at the ground if you turn around or things like that.
If I had to guess you both apologized when it happened, and both of you should be able to walk away satisfied after a random friendly interaction like that.
