Se 1: \( \mathrm{CA}> \) Chapter 9 : Measures of Varlation \( > \) section Exerclst Find the range of the data. \( 4.8,5.5,4.2,8.9,3.4,7.5,1.6,3.8 \) The range is \( \square \).

To find the range of the data, you simply need to subtract the smallest number from the largest number in your set. In this case, the largest number is 8.9, and the smallest is 1.6. So, the calculation goes: \( 8.9 - 1.6 = 7.3 \). Therefore, the range is \( 7.3 \). Range is a simple yet powerful statistic that gives you a quick idea of the spread of your data. It’s particularly useful in fields like finance or quality control, where understanding variability can guide decision-making. By looking at the range, you can quickly assess how much the data points diverge from one another, enabling you to identify outliers or significant gaps in the dataset.
