The mean is the best choice for calculating the average number of absences. It is a measure of central tendency that takes into account all observations and provides a representative value of the dataset. The median or the variance are not appropriate for this scenario, as the median only looks at the middle value and the variance measures the degree of spread or variability in the data. Correlation, on the other hand, would be used to measure the relationship between two variables.
