Mean = (4 + 3.5 + 6 + 7.2 + 5 + 6.1 + 3.6 + 7.1 + 3 + 3.2) / 10 = 4.96 cm
To find the median:
1. Arrange the data in ascending order: 3, 3.2, 3.5, 3.6, 4, 5, 6, 6.1, 7.1, 7.2
2. Since there are 10 data points, the median is the average of the middle two values.
Median = (4 + 5) / 2 = 4.5 cm
Therefore, the mean seedling height is 4.96 cm and the median seedling height is 4.5 cm.
