The mean is the best choice to estimate the average when data have been collected using an interval or ratio scale. It takes into account all the data values and their magnitudes, and is easily calculable using the formula ∑x/n, where ∑x is the sum of all the data values and n is the sample size. The mode is not suitable for interval or ratio data as it requires categorical data, while the median may not give an accurate representation of the average when extreme values are present. Maxima and trend are not measures of central tendency and do not provide an estimate of the average.
