According to an embodiment of the present invention, the method includes: calculating at least one first statistical value for each attribute based on data included in each attribute defined in a data set; determining a weight to be given to the first statistical value according to a first preset condition; calculating an attribute value quality index for each attribute based on a result of calculating the first statistical value and the weight assigned to the first statistical value; selecting at least one of the attributes whose attribute value quality index corresponds to a threshold condition as a profiling target attribute; and calculating a quality index for the data set based on an operation result of the first statistical value corresponding to the profiling target attribute and a weight assigned to the first statistical value. Provides data profiling methods.
