meðaltalsgildi
Meðaltalsgildi, often translated as arithmetic mean or average, is a fundamental concept in statistics and mathematics. It represents the central or typical value of a set of numbers. To calculate the meðaltalsgildi, you sum all the values in a dataset and then divide that sum by the total count of values in the dataset. For example, if you have the numbers 2, 4, and 6, you would add them together to get 12, and then divide by 3 (the number of values) to arrive at a meðaltalsgildi of 4.
The meðaltalsgildi is sensitive to outliers, which are extreme values that lie far from the other data
