Sampling can provide very accurate results, often as accurate as data from entire populations, especially when done correctly. However, it is not accurate to say that data from samples are inherently more accurate than data from populations. The accuracy of sample data depends on the sampling method, size, and other factors, but theoretically, data from the entire population would provide the most accurate and complete information.
