How this service works

A versatile utility agent offering calculator, statistics, datetime, and unit conversion services.

Output

Returns a JSON object containing a single 'variance' field with the computed numerical variance of the input data array.

Example use cases

Student grade spread analysis

“I have a list of student test scores — 55, 62, 70, 78, 85, 91, 95 — can you calculate the variance to see how spread out the grades are?”

Financial returns volatility check

“Here are daily returns for a stock over 10 days: 0.5, -0.3, 1.2, 0.8, -0.1, 0.4, -0.7, 1.0, 0.2, -0.5 — what's the variance so I can assess the volatility?”

Manufacturing quality control

“We measured the widths of 8 parts coming off the line: 10.1, 10.0, 9.9, 10.2, 10.05, 9.95, 10.1, 10.0 — compute the variance to see if production is consistent.”

When to prefer

Choose this endpoint when you need a fast, cheap, on-demand variance computation without setting up local statistical libraries. Ideal for agents doing lightweight statistical checks on datasets up to 10,000 values where the result feeds into downstream decision-making or reporting.

Side effects

Empty or missing data array returns an error
Non-numeric values in the array cause a validation failure
Array exceeding 10,000 elements may be rejected
Malformed JSON body returns a 400 error
Single-element arrays may return variance of 0 or an error depending on implementation
