While both "range" and "scope" relate to limits or extent, they differ in their specific application. "Range" typically refers to a variety of possibilities within a set of values, often numerical. "Scope" refers to the extent or area something affects or applies to, often more abstract. Think of "range" as the breadth of something concrete and "scope" as the breadth of something abstract.

Let's look at some examples:

• Range: "The range of temperatures today will be from 15 to 25 degrees Celsius." (Meaning: The temperatures will vary between 15 and 25 degrees.) "The car has a range of 500 kilometers on a single charge." (Meaning: The car can travel up to 500 kilometers before needing to recharge.)

• Scope: "The scope of the project is to build a new website." (Meaning: The project's goal is to create a new website.) "The scope of her knowledge is quite impressive." (Meaning: The extent of her knowledge is very impressive.)

Notice that "range" often involves measurable quantities. You can quantify the range of temperatures or the range of a car's travel. "Scope," on the other hand, often deals with more conceptual ideas, such as the scope of a problem or project, which are harder to measure precisely.

Here are a few more examples to illustrate the difference:

• Range: The price range of the smartphones is between $300 and $1000. (The smartphones have prices between $300 and $1000)
• Scope: The scope of the investigation includes all staff members. (The investigation will include all staff members.)

Sometimes, the words can be used interchangeably, but paying attention to the context will help you understand the intended meaning. Often, when dealing with quantifiable things, 'range' is a better fit, whereas 'scope' is better suited for qualitative things.
