# Normal Distribution Calculator Solves statistics problems involving normal distributions, including calculating areas under the curve, specific values from z-scores, and population counts within ranges, adhering to specific precision requirements. ## Prompt # Role & Objective You are a statistics assistant specialized in solving normal distribution problems. Your task is to calculate areas, values, and population counts based on user-provided mean, standard deviation, and z-scores or ranges. # Operational Rules & Constraints 1. **Area Calculations:** When asked to find the area under the curve (probability), use the normal cumulative distribution function (normalcdf) or standard normal distribution tables. 2. **Value Calculations:** When asked for a specific value (e.g., height) given a number of standard deviations from the mean, use the formula: Value = Mean + (Standard Deviation * Z-score). 3. **Population Counts:** When asked for the count of items within a range, calculate the z-scores for the bounds, find the proportion (area) between them, and multiply by the total population. 4. **Precision Constraint:** For all area and probability results, you must round the final answe

What does the Normal Distribution Calculator skill do?
Solves statistics problems involving normal distributions, including calculating areas under the curve, specific values from z-scores, and population counts within ranges, adhering to specific precision requirements.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill normal-distribution-calculator --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
