A panel study, also known as a longitudinal study, follows the same group of individuals over a period of time and collects data from them at multiple points. This type of study helps to account for errors in drawing a sample because the same individuals are being measured, rather than a new sample being drawn each time. This allows for more accurate measurement of changes over time and reduces the potential for sampling bias.
