Intermediate Topic 25 of 51 Math for Computing
Confidence Intervals
Ranges likely containing a true parameter.
How it works
A 95% CI is computed by a procedure that captures the true parameter in 95% of repeated samples, e.g. mean ± 1.96·σ/√n.
Where it is used
Reporting estimates with uncertainty.
Common pitfall
It does not mean 95% probability for this one interval.
Where it fits in the course
Confidence Intervals is topic 25 of 51 in Math for Computing, rated Intermediate. It follows Hypothesis Testing. The next topic is Linear Systems.
