This section will help us roughly estimate the mean and median measures of the distribution since we have lost some information about the specific data values.
Sometimes data is given in summarized format of a frequency or relative frequency distribution instead of as a list of individual values/characteristics.

As such, can one find our measures of center from such summarized format of the data? This section investigates that possibility in regard to the median and the arithmetic mean measures. Then, a short extension to the concept of "weighted" means is also discussed.
