To calculate the mean absolute deviation (MAD), Sarina first needs to find the mean of her data set. She will then subtract the mean from each data point to find the absolute deviations.

The number she will use for the divisor in the formula for the mean absolute deviation is the number of data points in her set.

In this case, Sarina has tracked her homework time for 7 days, which gives her 7 data points.

Therefore, the number she will use for the divisor is 7.
