WebA frequency distribution table in which we group the data is known as a grouped frequency distribution table. The table is based on the frequencies of class intervals. All the categories of data are divided into different class intervals of the same width, for example, 0–5, 5–10, 10–15, etc. And then the frequency of that class interval ... WebSummary. For grouped data, we cannot find the exact Mean, Median and Mode, we can only give estimates.; To estimate the Mean use the midpoints of the class intervals: . Estimated Mean = Sum of (Midpoint × Frequency)Sum of Frequency. To estimate the Median use: . Estimated Median = L + (n/2) − BG × w. where:
