![]() Therefore, the range of scores in Manila, Tokyo, and Berlin are 13, 8, and 5, respectively.Ĭonsider the boxplot and determine the range of the boxplot. Thus, getting the range in the scores of Manila, simply use the same formula in solving for the range. In this box plot, the scores in Manila range from 3 to 16. In boxplots, the minimum and maximum values appear at the ends of the whiskers except when there are outliers. Range in boxplotsīoxplots show data ranges for groups within a dataset. Therefore, the range of Distribution B is 80. Step 2: Find the range of the distribution. Step 1: Determine the upper and lower limit of Distribution B. ![]() Therefore, the range of Distribution A is 70.ĭetermine the range of the distribution below. Thus, 10 is the lower limit and 80 is the upper limit. Using the same formula of the range, determine the upper and lower limit. The blue line represents the range of Distribution A. The range in a histogram is only the approximate value since the data in a histogram is not the raw data values. The range in a histogram is determined by the width that the bar cover along the x-axis. To determine the range in a histogram, observe the highlighted blue line. Range can also be defined in several graphs, such as histograms, boxplots, and scatterplots. The value of the range cannot be negative.Be careful of data scores that have a frequency of 0, especially if it is in the upper and lower limits.Make sure that the data is in ascending or descending order.Step 2: Compute for the value of the range. Hence, we will not consider both of those numbers as part of the data set. However, the frequency of 500 and 50 is 0. In the frequency table, the highest entry is 500 and the lowest entry is 50. Step 1: Determine the lowest and highest score in the frequency table. The result of the study is translated into a frequency table. In a company survey, the employees were asked about their average monthly spending on transportation. Hence, we will not consider 10 as part of the data set. In the frequency table, the highest entry is 10 and the lowest entry is 1. The result of the study is shown in the frequency table below. The students were asked to answer a survey about the average number of hours they usually study on weekends. The column of age represents the scores of the data. Step 1: Determine the lowest and highest entry in the frequency table. ![]() The age of the Math Club members is represented in the frequency table below. Subtract the lowest entry from the highest entry. ![]() Find the lowest and highest entry in the frequency table.Make sure the entries in the score column are in ascending or descending order.Calculating the range of a frequency table Step 2: Find the range of the data set using the formula. Step 1: Determine the lowest and highest value in the data set. The scores of the students on their recent math quiz are listed in the table below. Therefore, the range of the data set is 56. Step 2: Determine the minimum and maximum value. Step 1: List all the first 15 multiple of 4. What is the range of the data set Jisoo has? Jisoo listed the first 15 multiples of 4 and decided to find the range. Therefore, the price range of strawberries is $13. Given the highest value = $18 and the lowest value = $5 What is the price range of strawberries in the market? She found out that the highest price of 1-kilogram strawberry costs $18 and the lowest price costs $5. Jennie compared all the prices of 1-kilogram strawberries in the market. Subtract the minimum value from the maximum value.Determine the lowest and highest value of the data set.To calculate the range of ungrouped data, Thus, to calculate the range of a data set, Range = Maximum Value – Minimum ValueĬalculating the range of an ungrouped data The range of a data set is simply the difference between the maximum and minimum values. The range can be measured if given ungrouped data, frequency distribution table, graphs such as histogram, boxplot, and scatterplots. The range is the easiest measure of variability to calculate and interpret. It is the most straightforward measure of variability. In statistics, a range is the spread of data from the minimum and maximum value in the distribution. properly determine when to use the range.know the limitations of using range given a data set and.solve for the range of a frequency table.properly define the range in statistics.How to interpret the range of the data set?Īfter reading this article, you will be able to:.Calculating the range of a frequency table.Calculating the range of an ungrouped data.
