Which statistical method is commonly used for data quality assessment?

Descriptive statistics are commonly used for data quality assessment as they provide a summary of the key characteristics of a dataset, such as measures of central tendency (mean, median, mode), dispersion (range, variance, standard deviation), and distribution (histograms, box plots). These statistics help analysts understand the underlying patterns, trends, and outliers in the data, enabling them to assess data quality and make informed decisions based on the findings.
