The mean is the best choice when the distribution is symmetrical and the scale of measurement is interval or ratio. This is because the mean takes into account all the values in the distribution, and is affected by extreme values or outliers, which can have a greater impact on the mean than on other measures of central tendency. When the distribution is skewed, it is often better to use the median as a measure of central tendency, as it is less affected by extreme values. When the scale of measurement is ordinal, the mode may be a better choice as it reflects the most frequently occurring value.
