Point Estimate Calculator

Estimate a population proportion using several methods.

MLE estimate 0.4
Laplace estimate 0.402
Wilson estimate 0.4037

Formula: MLE = x/n; Laplace = (x+1)/(n+2); Wilson midpoint

Step-by-step with your numbers:
1. Values used:
2. Successes = 40
3. Trials = 100
4.
5. MLE estimate = Successes / Trials = 40 / 100 = 0.4
6. Laplace estimate = 0.402
7. Wilson estimate = 0.4037
Did we solve your problem today?

A point estimate is a single best guess for a population proportion.

The math behind it

The MLE is x/n. Laplace and Wilson estimates shrink extreme proportions toward 0.5 for stability.

Worked example

40 of 100 gives MLE 0.40, Wilson about 0.404.

FAQ

Why use Wilson?

It behaves better than the simple proportion for small samples or extreme values.
