Number the entries in the table 1–51 (Includes Washington, DC; Numbered vertically)Step 1: Arrange the data values in ascending or descending order. Step 2: Now, determine the lowest and the highest value in the given dataset. Step 3: Finally, find the difference between the highest and lowest data values. Step 4: The resultant value obtained in step 3 is known as the range of the given dataset.

Step 1: Arrange the data in ascending or descending order. Step 2: Let the total number of observations be n. To find the median, we need to consider if n is even or odd. If n is odd, then use the formula: Median = [ (n + 1)/2] th observation. Example 1: Let's consider the data: 56, 67, 54, 34, 78, 43, 23.
