Reliability (statistics)

Reliability (statistics) is a way to measure how accurate a set of measurements is. It means that the measurements should produce the same results each time they are taken. To measure reliability, scientists look at how consistent the results are over time. For example, if they measure the same thing ten times and get the same results, then the measurement is considered to be reliable. It's important that measurements are reliable so that scientists can trust the data and make decisions based on it.
