This study investigated the validity of three curriculum-based measures for predicting the performance of secondary students on content-area tasks. Secondary data analysis is different than primary data analysis where the same individual or team designs, collects, and analyzes data for their own purposes. You are doing a historical study - that is, your study begins and ends at a particular point in time. Most of the studies exploring evidence for validity of secondary retail food data have used on-site verification and have not conducted analysis by data source (e.g., sensitivity of Reference USA) or . You are covering an extended period, and analysing development over that period - a longitudinal study. During your evaluation process, consider the following factors: The data provider's purpose. 3. 8. 1.Purpose: how it relates to current research objective 2 . More than half of the studies (53%) did not report evidence for validity by type of food outlet examined and by a particular . The basics to test secondary data could be purpose, accuracy, consistency, credibility, methodology, and bias. Assess the reliability of your source if an outlier data point is coming from a historically well-regarded firm or organization, investigate to determine whether or not they've accounted for something the other sources failed to. Secondary data is available from a variety of sources, such as governments and research institutions. Secondary data generally have a pre-established degree of validity and reliability which need not be re-examined by the researcher who is re-using such data. important to critically analyze official statistics for accuracy and validity. One of these threats is the sampling approach employed in selecting the participants for the study. The study believes that the use of the adjusted inter-raters/observer as proposed by the study will add value to the method of assessing the reliability of SD, because of it use of statistical tools to directly estimate the available data. More than half of the studies (53%) did not report evidence for validity by type of food outlet examined and by a particular secondary data source.
