   • Mean, Median and Mode of Grouped Data

     Suppose we want to compare the age of students in two schools and determine which school has more aged students. If we compare on the basis of individual students, we cannot conclude anything. However, if for the given data, we get a representative value that signifies the characteristics of the data, the comparison becomes easy. 

     A certain value representative of the whole data and signifying its characteristics is called an average of the data. Three types of averages are useful for analyzing data. They are: 

     • Mean
     • Median
     • Mode

     In this article, we will study three types of averages for the analysis of the data.

     Mean

     The mean (or average) of observations is the sum of the values of all the observations divided by the total number of observations. The mean of the data is given by x = f1x1 + f2x2 + …. + fnxn/f1 + f2+… + fn. The mean Formula is given by,

     Mean = ∑(fi.xi)/∑fi

     • l = lower limit of median class.
     • h = width of median class.
     • f = frequency of median class, 
     • cf = cumulative frequency of the class preceding the median class.
     • N = ∑fi
     • xk = lower limit of the modal class interval.
     • fk = frequency of the modal class. 
     • fk-1= frequency of the class preceding the modal class.
     • fk+1 = frequency of the class succeeding the modal class.
     • h = width of the class interval.
     • First, we mark the upper limits of class intervals on the horizontal x-axis and their corresponding cumulative frequencies on the y-axis.
     • Now plot all the corresponding points of the ordered pair given by (upper limit, cumulative frequency).
     • Join all the points with a free hand.
     • The curve we get is known as ogive.
     • On joining these points successively by line segments, we get a polygon, called a cumulative frequency polygon.
     • On joining these points successively by smooth curves, we get a curve, known as less than ogive.
     • More Than Ogive

   • Median of Grouped Data: Formula, How to Find, and Solved Examples

     Median of Grouped Data is the value of the middlemost data point in any dataset when dataset is grouped. For ungrouped data, it is easy to find the median but finding the Median of Grouped Data is slightly complex. When we have any data in statistics, we try to find some basic parameters related to it which provide ease in data interpretation and making further predictions related to data. To measure the central tendency of data, i.e., a single value that can be used to represent an entire distribution, we generally have three parameters: mean, median, and mode.

     In this article, we will discuss what is meant by Grouped Data and Median of Grouped Data. We will also learn about the Formula for Median of Grouped Data and steps to calculate the Median of Grouped Data, solved examples, and some frequently asked questions as well.

   What is the median of a distribution?

   • Median of any distribution is that value that divides the distribution into two equal parts such that the number of observations above it is equal to the number of observations below it. Thus, the median is called the central value of any given data either grouped or ungrouped.

   Jun 4, 2024 · Mean for ungrouped data, also known as the arithmetic mean ([Tex]\bar{x}[/Tex]), is calculated by summing up all individual values in the dataset and dividing the sum by the total number of values. This provides a single representative value that reflects the central tendency of the data.

   1 day ago · The midpoints of each group would be: Group 1: 15 Group 2: 25 Group 3: 35 Group 4: 45. If the total number of data points is 10, and the highest frequency is in Group 2 and Group 3, the median would be the average of the two midpoints (25 + 35)/2 = 30.
