The values of a variable resistor can be changed or varied over a range.

Explanation:
A variable resistor is built to adjust its resistance. When you turn a knob or move a slider, a wiper or contact changes the length of the resistive path, so the resistance value between the terminals can continuously increase or decrease over a range. This lets you tune how much current flows in a circuit or how voltage is divided, which is exactly why such components are used in controls like volume knobs or light dimmers. So the statement is true—the resistance value can be varied over a range.
