Let's try to look at the dispersion this time. We have data set as follows: [5, 6, 3, 5, 7, 8] Based on this data, we want to calculate the range. To do this, you need to find the largest number in the dataset, which is . Then, you need to find the smallest number in the dataset, which is . The difference between these two numbers is . Therefore, the range of this dataset is
