Here's the breakdown:

* Resistivity is a measure of a material's resistance to the flow of electric current. Higher resistivity means higher resistance, which means the material will hinder the flow of electricity more.

* Conductivity is the opposite of resistivity. It measures how easily a material allows electricity to flow through it. Higher conductivity means lower resistance, indicating that the material is a good conductor.

Therefore, a material with high resistivity is a poor conductor of electricity.

Think of it this way:

* High resistivity = like a narrow, winding road, making it hard for cars (electrons) to travel.

* Low resistivity = like a wide, straight highway, allowing cars (electrons) to travel easily.
