The data were compared according to the mean, mode, median and variance
Mean: reflects the average size of a group of data, commonly used to represent the overall "average level" of the data. Median: like a dividing line, divides the data into the first half and the second half, so it is used to represent the "medium level" of a group of data. Mode: reflects the data with the most occurrences, which is used to represent a group of data
