Example Data Table
| Dataset | Values | Minimum | Maximum | Range |
|---|---|---|---|---|
| Class Test Scores | 14, 18, 21, 9, 27, 11 | 9 | 27 | 18 |
| Temperature Readings | -2, 4, 8, -5, 7, 1 | -5 | 8 | 13 |
| Production Output | 120, 118, 130, 115, 127 | 115 | 130 | 15 |
Formula Used
Minimum: min(x) = the smallest value in the dataset.
Maximum: max(x) = the largest value in the dataset.
Range: range = max(x) − min(x).
Mean: mean = (sum of all values) ÷ n.
Median: the middle value after sorting, or the average of the two middle values when n is even.
Variance: variance = Σ(x − mean)² ÷ n.
Standard Deviation: std dev = √variance.

FAQs
1) What does this max min finder calculate?
It finds the smallest and largest values in your list. It also reports range, mean, median, variance, standard deviation, sorted values, and optional frequency data for deeper analysis.
2) Which separators can I use for numbers?
You can separate values with commas, spaces, semicolons, or line breaks. Mixed separators also work, which helps when pasting data from spreadsheets or notes.
3) What happens to invalid entries?
Any non-numeric item is ignored during calculation. After submission, the calculator lists invalid entries so you can review and correct the input quickly.
4) What is absolute value mode?
Absolute mode changes every number to its distance from zero before calculation. This is useful when you care about magnitude rather than positive or negative direction.
5) Why would I remove duplicates?
Removing duplicates helps when repeated values would distort summaries. It can be useful in set-based maths tasks, unique observations, or simplified exploratory analysis.
6) Does the chart update with my values?
Yes. After submission, the graph plots your processed values in order and highlights the detected minimum and maximum points for easier visual inspection.
7) Can I export the result?
Yes. You can download the generated result as CSV for spreadsheet work or as PDF for sharing, printing, documentation, or recordkeeping.
8) Is this useful beyond maths class?
Yes. It helps with score reviews, financial checks, process monitoring, measurement comparisons, quality summaries, and any dataset where extremes matter.
