Step-by-Step: Mean, Median, Mode
- Mean: Add all values and divide by the count.
- Median: Sort the values and take the middle one (average the two middle values if the count is even).
- Mode: Identify the most frequently occurring value.
Worked Example
Data set: 4, 8, 6, 8, 10
Mean = (4+8+6+8+10)/5 = 36/5 = 7.2
Sorted: 4,6,8,8,10 → Median = 8
Mode = 8 (appears twice)
Frequently Asked Questions
What if a data set has two modes?
It's called "bimodal" — both values are equally valid modes, and this often signals two distinct subgroups mixed within the data.
What if my data set has an even number of values?
Average the two middle values after sorting to find the median — there's no single middle number when the count is even, so this average serves as the median instead.
