When the student moves the end of the compressed coiled spring faster while keeping everything else the same, the characteristic that will increase is frequency.

Frequency refers to the number of waves that pass a point in a given time period. If she moves the end of the spring faster, more complete waves will be produced in that same time frame, resulting in a higher frequency.

So, the correct response is frequency.
