Let's see how we can reduce the width of a confidence interval.
You could reduce the width by increasing the precision of the measures you realize (in the case where the confidence interval represents some measure).
First, a brief definition of what a confidence interval is.
A confidence interval refers to a pair (or various pairs) of numbers such that between these numbers include a given parameter (at least in average).
A quick example, if we say that the confidence interval for the mass of a given object is (1g, 3g) this means that the mass of that object is some value between 1 gram and 3 grams.
Then, if we want to decrease that interval, then we must be more precise with our measures.
To do this we can use better tools (the more precise the tools, the smaller confidence interval we get).
Note that this is just a really general example, as confidence intervals can be used in a lot of different experiments, thus there are a lot of different ways of reducing the width.
