Subtract the smallest number from the largest number: 10 - 3 = 7.

Step 4:

Therefore, the range is 7.

Supplemental Knowledge:

The range is a measure of dispersion which indicates the spread of data within an array. To calculate it, subtracting the smallest value in your dataset from its largest one and divide by 2.

From Concepts to Reality:

Understanding range can be particularly useful in real-life applications such as analyzing test scores, financial information or any other numerical set. For instance, knowing the range can give a clear picture of any changes that occurred within that week in terms of temperature variations.

Understanding sales figures can provide businesses with invaluable information regarding periods of high and low performance, which is crucial when making important business decisions.
