👉 Discrepancies are differences or variations in values, quantities, or elements between two or more sets of data. They can be caused by measurement errors, rounding errors, imprecision in measurements, or other factors that cause the results to differ from what would be expected if the data were measured exactly. Discrepancies can occur because a sample is not representative of the population, there is an error in the measurement process, or due to statistical fluctuations or sampling variability.
