To find the mean, add all the seedling heights together and divide by the total number of measurements:
Mean = (4 + 3.5 + 6 + 7.2 + 5 + 6.1 + 3.6 + 7.1 + 3 + 3.2) / 10
Mean = 48.7 / 10
Mean = 4.87 cm
To find the median, first arrange the measurements in ascending order:
3, 3.2, 3.5, 3.6, 4, 5, 6, 6.1, 7.1, 7.2
Since there are 10 measurements, the median will be the average of the 5th and 6th measurements:
Median = (4 + 5) / 2
Median = 4.5 cm
Therefore, the mean seedling height is 4.87 cm and the median seedling height is 4.5 cm.
