Precise instructions for any process are like a formula or a recipe to follow in order to get the same results each time.

Output

alexandrashockey — 2024-10-24 12:34:11 UTC

Value that is produced by an algorithm.

Histogram

alexandrashockey — 2024-10-24 12:35:00 UTC

A histogram shows the frequency (or percent) of all the values that fall in a certain range, called a bin.

Bin

alexandrashockey — 2024-10-24 12:35:31 UTC

A bar whose height corresponds to how many data points are in that bin.

Bin Width

alexandrashockey — 2024-10-24 12:37:43 UTC
