Mean, median, mode, range, and standard deviation all calculated instantly.
Mean is sensitive to outliers. Median is more robust — use it for skewed data like salaries. Mode is the most frequent value. Standard deviation measures how spread out values are from the mean.
Mean is the arithmetic average — sum divided by count. Median is the middle value. For skewed data (e.g. salaries), median is more representative because a few very high values pull the mean up.
How spread out the numbers are from the mean. Low std dev = values clustered near mean. High std dev = values spread widely. Two datasets can have the same mean but very different std deviations.
A dataset can be bimodal (2 modes) or multimodal (3+ modes). This calculator shows all values that appear most frequently.
Yes — enter your class marks separated by commas. The mean gives the class average, median shows the midpoint, and std dev shows how spread the marks are.
Mean = (5+10+15+20+25) / 5 = 75 / 5 = 15. The median is also 15 (the middle value). The mode does not exist as all values appear once.
