Statistical operations with AddUp are performed with a set of functions that apply to a list of numbers or arbitrary length. Statistical functions provide summary information on the content of the list. Each function accepts a lists of arguments containing as many numbers as needed to represent a group under statistical study.

Statistical functions include:

avg or mean

Returns the average (or mean) of a list of values. It returns 0 on an empty list, or the average value if the list is not empty. The average or mean is the sum of all values in a list divided by the item count.

avgG

Returns the geometric average of a list of values. It returns 0 on an empty list, or the geometric average value if the list is not empty. The geometric average of a list of values is the result of adding the square of all values (eg. using the sum2 function) and extracting the 'count' root of this sum.

count

Returns the count of values in a list (the total number of items). It returns 0 on an empty list, or the number of arguments if the list is not empty.

gcd or gcf

Returns the greatest common denominator (greatest common factor) of all values in a list. It returns 0 on an empty list, or the greatest common denominator of all values if the list is not empty.

lcm

Returns the least common multiple of all values in a list. It returns 0 on an empty list, or the least common multiple of all values if the list is not empty.

max

Returns the maximum value contained in a list. It returns 0 on an empty list, or the value of the largest argument if the list is not empty.

median

Returns the median of a list of values. It returns 0 on an empty list, or the median value if the list is not empty. The median value is the value that is at the center position of a list after it is sorted. For lists containing an even number of values, it is the average of the values found at the two middle positions.

min

Returns the minimum value contained in a list. It returns 0 on an empty list, or the value of the smallest argument if the list is not empty.

prod

Returns the product of all values contained in a list. It returns 0 on an empty list, or the product of all values if the list is not empty.

sd

Returns the sample standard deviation of a list of values. It returns 0 on an empty list, or the sample standard deviation if the list is not empty.

sdP

Returns the population standard deviation of a list of values. It returns 0 on an empty list, or the population standard deviation if the list is not empty.

sum

Returns the sum of all values contained in a list. It returns 0 on an empty list, or the sum of all values if the list is not empty.

sum2

Returns the sum of the square of all values contained in a list. It returns 0 on an empty list, or the sum of the square of all values if the list is not empty.

var

Returns the sample variance of a list of values. It returns 0 on an empty list, or the sample variance if the list is not empty.

varP

Returns the population variance of a list of values.It returns 0 on an empty list, or the population variance if the list is not empty.
