🧪 Marketing Market Research Simulation

This simulation demonstrates how market-research teams estimate what a whole target audience prefers by surveying only a small random sample of it. A virtual population of consumers is rendered in 3D, each secretly preferring Product A or Product B according to a true population proportion you control. Draw one sample at a time — or let the simulator auto-sample continuously — to see a random subset of respondents highlighted, the sample's preference proportion p̂ computed live, and its margin of error and confidence interval reported exactly as a real survey report would. A growing histogram shows the sampling distribution of p̂ itself converging toward the true value as more surveys are run, making the Central Limit Theorem and the 1/√n cost of precision visible and interactive rather than abstract.
