Only the Grouped Frequency Table survived ... can we help Alex calculate the Mean, Median and Mode from just that table?The answer is ... no we can't. Not accurately anyway. But, we can make estimates.Estimating the Mean from Grouped DataSo all...
Grouped frequency tables are very useful for picturing larger amounts of data. However, they are not ideal for finding the mean, median, and mode of data because we can't tell what the actual original raw data is from a grouped frequency table. Therefore, we will mostly be using categorica...

In these lessons, we will learn: how to find the median of a frequency table when the number of observations is odd. how to find the median of a frequency table when the number of observations is even. how to find the median for both discrete and grouped data. ...
The median is the middlemost number of a group of numbers that have been arranged in order by size. Learn how to find median for ungrouped and grouped data using different formulas along with solved examples here at BYJU'S.
Finding Median from Frequency TableIf we are given a frequency table, to find the median, what we do first is sum the frequencies to determine the number of observations. If the sum, say n, is odd, then the median is located at the (n+12...
1. The following table represents the frequency distribution of the number of children per family for 100 families in a locality: Find the median number of children per family. 2. Find the median of the following frequency distribution:
Answer. Median of grouped data is the data formed in a frequency distribution table in ascending order with the valu...Read full What Makes the Median a Positional Average? Answer. When the data are presented in either an increasing or decreasing order, the median is where the data fall....
Grouped data is represented in a frequency distribution table with the data grouped as classes, and each class having a frequency against it. Here, to calculate the median, we find the cumulative frequency, and wherever the middlemost observation occurs, is the median cla...
