AI explanation
Formula
Mean = Sum / Count; Median = middle value (or average of the two middle values); Mode = most frequent value(s)Worked example
2, 4, 4, 4, 5, 5, 7, 9
| Field | Value |
|---|---|
| Numbers | 2, 4, 4, 4, 5, 5, 7, 9 |
| Mean | 5 |
| Median | 4.5 |
| Mode | 4 |
| Count of numbers | 8 |
Assumptions
- If every value in the list is unique, the mode is reported as "No mode".
- If multiple values tie for the highest frequency, all of them are reported as modes.
Frequently asked questions
What's the difference between mean, median, and mode?
Mean is the sum divided by count. Median is the middle value when sorted (or the average of the two middle values for an even count). Mode is the most frequently occurring value.
Why would I use median instead of mean?
Median is less affected by outliers than mean — for example, income or house-price data is often summarized with median rather than mean because a few extreme values can skew the mean.
Can a list have more than one mode?
Yes — if two or more values tie for the highest frequency, the list is "multimodal" and all of the tied values are reported.
