Quizplus · Accepted Answer

Confidence intervals are the range of values within which the population parameter is expected to fall with a certain level of confidence. They reflect the degree of accuracy desired by the researcher and are typically set at a certain level, such as 95% or 99%. Measures of variability, standard percentages, parameter estimates, and statistical inferences are all related to statistical analysis but do not directly relate to the range of confidence desired by the researcher.
