So I understand the concept of a distribution. I just don’t understand the concept of a standard deviation from the mean of that distribution. How can we tell what is 1 standard deviation away as opposed to 2 standard deviations?
I’d be very thankful for an explanation, thank you :).

The mean tells you where the distribution is centered. The standard deviation tells you how wide or dispersed that distribution is. Note that there are different ways of measuring distribution center and spread (for example, median, range, absolute deviation, mode), each of which has their pros and cons.
