All three measures of central tendency at once — mean, median and mode — plus range.
mean = Σx/n · median = middle value · mode = most frequent value
Data set 3, 5, 5, 8, 9, 15 → mean = 45/6 = 7.5, median = (5+8)/2 = 6.5, mode = 5.
Use the mean for balanced data without outliers, the median for skewed distributions like house prices or salaries, and the mode for categorical-style questions such as the best-selling shoe size.
If every value appears once the data has no mode. If several values tie for most frequent, all are reported as modes (bimodal or multimodal data).
Decimals are fully supported — enter them exactly as written.
Large gaps between values skew the mean toward the extremes while the median stays anchored to the middle observation.
