... • A 95% confidence interval will contain the true parameter (e.g., the population mean) 95% of the time if repeated random samples are taken. • It is impossible to say whether it is successful or not in any particular case, i.e., we know that the CI will usually contain the true mean under random sa ...

... distribution for a sample of 100 will be close, but not the same as your neighbors. • The larger the sample size we have the less the spread (variance, range, IQR, etc) of the distribution • We know that some statistical measures are affected by outliers and some are not. Outliers will cause problem ...
