Statistics

Number of values (count) The total number of values in the range entered
Total value of numbers(sum) The total sum of all the values
Mean (Average) The Mean is the average of a range of numbers.
Median (Middle Value) The Median is the middle number in a sorted list of numbers. It is also known as the second percentile (Q2)
Minimum The smallest value in the range
Maximum The largest value in the range
Variance The sum of the squared differences between each value and the mean divided by the number of items
Standard Deviation Standard Deviation is calculated as the square root of the varience
Mode - Most frequent value(s)
1st Quartile (25%) The first quartile (Q1) is the middle number between the smallest number and the median in a sorted list of numbers (also known as the lower quartile)
3rd Quartile (75%) The third quartile (Q3) is the middle number between the median and the highest number in a sorted list of numbers (also known as the upper quartile)
Percentile (1 to 100) A percentile indicates the value in a sorted list at a certain percentage of the range. e.g. the 25th percentile is the value at 25% of the range

This calculator includes the following algorithms

The Mean (or Average) is calculated by adding all the values together, then dividing this by the number of values

The Median is calculated by sorting the values in order then selecting the value in the middle of the list

The Mode is the most frequent value in the range (there can be more than one value)
