What the statistics solver can do
Center
mean, median, mode
Which average to use and why.
Spread
variance & standard deviation
Sample (n − 1) and population (n).
Position
quartiles & IQR
Five-number summary.
Counting
nCr, nPr, n!
Combinations and permutations.
Probability
binomial probability
Exactly, at most and at least k successes.
Events
P(A ∪ B)
Addition, multiplication and complement rules.
Accuracy by design
A math engine first. AI second.
Chatbots guess. We compute, verify, and then explain — so every explanation is about a correct answer.
- 01
Understand
Your input — text, LaTeX, keyboard or photo — is normalized and classified into one of 20+ problem types.
- 02
Compute
A symbolic math engine solves it exactly: algebra, calculus, matrices, statistics.
- 03
Verify
Independent checks confirm the answer: substitution, numerical differentiation & integration, round-trips.
- 04
Explain
AI explains each verified step at your level — and can never change the answer.
Sample or population?
We report both. Use the sample standard deviation (divide by n − 1) when your data is a sample of a bigger group, and the population version (divide by n) when you have every value.
