Which phrase would you use to indicate that a data category did not change?

• A. Remained constant
• B. Levelled off
• C. Plateaued
• D. Stayed the same

Answer: (B)

Describing a trend that has stopped moving and settled at a stable value is the key idea here. When you say that something has levelled off, you’re signaling that the data stopped changing after a period of movement and then stayed at about the same level. This makes it a natural, precise way to describe a plateau in a chart or table.

The other phrases can fit in some situations, but they don’t capture the idea of a change that has ceased after movement as cleanly. “Remained constant” or “stayed the same” suggest no change throughout the entire period, which can feel too static if the chart showed a prior rise or fall before leveling. “Plateaued” is close and common in science, but can sound more technical or imply a longer, sustained flat period. Levelled off strikes a balanced, everyday-English way to indicate that values have stopped changing and are now stable.
