To find the mean absolute deviation, first find the mean of the dataset:

(4.8 + 5.9 + 6.2 + 10.8 + 1.2 + 6.4) ÷ 6 = 5.7

Next, find the absolute deviation of each value from the mean:

|4.8 - 5.7| = 0.9

|5.9 - 5.7| = 0.2

|6.2 - 5.7| = 0.5

|10.8 - 5.7| = 5.1

|1.2 - 5.7| = 4.5

|6.4 - 5.7| = 0.7

Then, find the mean of these absolute deviations:

(0.9 + 0.2 + 0.5 + 5.1 + 4.5 + 0.7) ÷ 6 ≈ 2.5

Therefore, the mean absolute deviation of the dataset is approximately 2.5.

To find the sum of the absolute deviations, first subtract the mean from each data point:

|63 - 47.9| = 15.1

|25 - 47.9| = 22.9

|74 - 47.9| = 26.1

|52 - 47.9| = 4.1

|63 - 47.9| = 15.1

|12 - 47.9| = 35.9

|46 - 47.9| = 1.9

Then, sum these absolute deviations:

15.1 + 22.9 + 26.1 + 4.1 + 15.1 + 35.9 + 1.9 = 121.1

Therefore, the sum of the absolute deviations of the dataset is approximately 121.1.
