Answer
View full question & answer→The median of an ungrouped data and the median calculated when the same data is grouped are not always the same because the median for ungrouped data is calculated by arranging the data in increasing or decreasing order. But for calculating the median of a grouped data, the formula used is based on the assumption that the observations are uniformly distributed in the classes.
