The questions below cover the definition, the even-count average, and how extra statistics are computed.
Questions
What is a median?
After sorting, it is the middle value — or the average of the two middle values when the count is even.
Why is my median not in the list?
Even count: the two centre numbers were averaged.
Mean or median for salary data?
Median, if a few very high salaries would distort the average.
Are files uploaded?
No. Computation stays in the tab.
Can I enter thousands with a comma?
A pattern like 1,200 is read as 1200. Use spaces or new lines between separate observations.
What is IQR?
Q3 − Q1, the spread of the middle 50% of the sorted list.
Is the sample standard deviation Bessel-corrected?
Yes: divide by n − 1 when n ≥ 2.
Geometric mean?
Shown only when every value is positive.
