Range Of Grouped Data Example

Example Newspapers. These are the numbers of newspapers sold at a local shop over the last 10 days 22, 20, 18, 23, 20, 25, 22, 20, 18, 20 Now calculate an approximate group size, by dividing the range by how many groups you would like. the data is continuous,

Answer To find the range of grouped data, subtract the lowest value in the dataset from the highest value within each group. Example Let's say you have grouped data representing the ages of individuals in different age groups 0-10, 11-20, 21-30, and so on. To find the range for each group, you would determine the highest and lowest ages

In the case of continuous frequency distribution or grouped data, the range is defined as the difference between the upper limit of the maximum interval of the grouped data and the lower limit of the minimum interval. Example 3 Calculate the range for the given frequency distribution. Class Interval 10 - 20 20 - 30 30 - 40 40

Range -Grouped Data Step 1 Construct the cumulative frequency distribution. Step 2 Decide the class that contain the median. Class Median is the first class with the value of cumulative frequency equal at least n2. Example Based on the grouped data below, find the mode. L mo

Calculating the Sample Mean for Grouped Data. When you have a frequency table or other group of data, the original set of data is lost replaced with statistics for the group. You can't find the exact sample mean as you don't have the original data but you can find an estimate. The formula for estimating the sample mean for data that

Example 3 Grouped Data If the smallest value in a class interval is 10 and the largest is 70, find the range. 1. Maximum 70 2. Minimum 10 3. Yes, the range can be calculated for grouped data by subtracting the lowest class boundary from the highest class boundary. However, since grouped data represents intervals, the range may be

Here is how to calculate the range of this grouped data using each formula Formula 1 Use Upper and Lower Limits. Range of Grouped Data U max - L min Range of Grouped Data 50 - 1 Range of Grouped Data 49 Using this formula, we estimate that the range is 49. Formula 2 Use Midpoints. Range of Grouped Data Midpoint max

Finding the Range From a Grouped Frequency Table. To find the range from a grouped frequency table, we look for the largest and smallest possible values. In our example, the largest possible value is the top of the oldest group, 100, while the smallest possible value is the bottom of the youngest group and so is 0. The range is therefore 100

In the case of grouped data, the range is the difference between the upper boundary of the highest class and the lower boundary of the lowest class. It is also calculated by using the difference between the mid points of the highest class and the lowest class. Example The following are the wages of 8 workers in a factory. Find the range
