Median of Grouped and Ungrouped Data


Finding Median for Ungrouped Data : Here we are going to see some practice questions on finding median for ungrouped data. Median is the value which occupies the middle position when all the observations are arranged in an ascending or descending order.


To determine the median of ungrouped data with N elements, one should first order the data from lowest to highest. The median is determined by finding either the middle element in the data or the average of the middle two elements, depending on whether there are an odd or even number of elements in the data. For example, suppose a set of data ...


I have 7 data values. The median is the value (7+1)/2 = 4th value from left or right which is 5. For an even number of data values, you will need to calculate the median and it may not be a data ...


For an even number of data values, you will need to calculate the median and it may not be a data value. It will be the mean of the two center values. Use the formula n/2 to get the left most value.


19.5.3. Median of an Ungrouped Data Set The median refers to the middle data point of an ordered data set at the 50% percentile.If a data set has an odd number of observations, then the median is the middle value. If it has an even number of observations, the median is the average of the two middle values.


Rank the values from low to high (or high to low; it doesn’t matter). If there are, say, 969 values, rank them from the lowest to the highest. The median is the 485th value. The formula is: median = (n+1)/2. So if there are 969 values, the formula...


Ungrouped data is the type of distribution in which the data is individually given in a raw form. For example, the scores of a batsman in last 5 matches are given as 45,34,2,77 and 80. Deduction of range and mean deviation from this data will help us to conclude his form and performance.

This formula is used to find the median in a group data with class interval. The median is the value of the data in the middle position of the set when the data is arranged in numerical order. The class where the middle position is located is called the median class and this is also the class where the median is located. This formula is used to ...
