Mean, median and mode explained
The arithmetic mean is the sum of all values divided by the number of values. The median is the middle value after sorting the dataset, or the average of the two middle values when the count is even.
The mode is the most frequently occurring value. Toolmera can report multiple modes when several values share the same highest frequency; if every value occurs only once, it reports No mode.

When median can be more useful than mean
The mean reacts strongly to extreme values because every number contributes directly to the total. The median depends on position rather than magnitude, so it can better represent the center of a highly skewed dataset.
Toolmera shows both so you can compare the arithmetic center with the ordered middle of the data.
