A doctoral student wants to determine the relationship between steps per minute and the time it takes to walk 100 feet in minutes. Thirty trials are completed and the correlation between steps per minute and time in minutes is determined to be -0.543. Therefore, fewer steps per minute were related to longer time spans. How is the correlation affected if the units for time are changed from minutes to seconds?
A-the correlation and time measurement would change proportionally to one another.
B-the correlation would increase because changing the units for time would result in an increase in time values.
C-It is impossible to determine the amount of change experienced by the correlation.
D-the correlation would decrease because only the units for one of the variables changed.
E-the correlation would stay the same because the change in units for time would have no effect on it.
