To calculate the mean absolute deviation (MAD), you need to find the average of the absolute deviations from the mean. The divisor used in this calculation is the number of data points.

In Sarina's case, she has tracked her time for 7 nights, so the divisor is 7.

Therefore, the correct response is:

7
