Question

Example 1 : Consider the marks obtained by 10 students in a mathematics test 42 25 78 75 62 given below: 55 36 95 73 60 The data in this form is called raw data. descending By looking at it in this form, can you find the highest and the lowest marks? Did it take you some time to search for the maximum and minimum scores? Wouldn't it be less time consuming if these scores were arranged in ascending or order? So let us arrange the marks in ascending order as 25 36 42 55 60 62 73 75 78 95 Now, we can clearly see that the lowest marks are 25 and the highest marks are 95 The difference of the highest and the lowest values in the data is called the range of se data. So, the range in this case is 95 – 25 = 70. Presentation of data in ascending or descending order can be quite time consuming particularly when the number of observations in an experiment is large, as in the case of the next example.​
