Question

Quizplus · Accepted Answer

Invalid data are values that are impossible, such as negative values for age or weight, or values that fall outside the expected range for a variable. Data that don't fit your theory may be unexpected, but they are not necessarily invalid. Outliers may be valid data points, but they can also be a sign of measurement error or inaccurate data. Missing data are simply data points that are not present, and may or may not be invalid.
