The two values that define the confidence interval.
Two numbers based on a statistical sample that set upper and lower limits on a figure at a specified probability level. Example: If the 90-percent confidence limits on the mean of sampled tilt error are 1.4° and 2.0°, in repeated measurements under identical conditions the mean should fall within these limits 90% of the time.
The highest and lowest boundaries in a confidence interval. As used here, a confidence interval accounts for the possibility that different groups of individuals might have different risk estimates even if they have the same range of dose estimates. Because there is uncertainty in risk estimates that are made for different radiation dose levels, scientists often include a confidence interval with a risk estimate.
