Data Validation is the process of checking if research information is accurate, complete, and reliable before it can be used in scientific studies. Think of it like quality control for information - making sure all the numbers and facts collected are correct and trustworthy. This is crucial in research because wrong data can lead to incorrect conclusions. Scientists and researchers use various methods to check their data, from simple checks (like making sure numbers are within reasonable ranges) to complex statistical tests. This process is similar to how a restaurant inspector checks food quality, but instead of food, researchers are checking the quality of their collected information.
