Step 1
Answer
The mode is the most frequently occurring value in the dataset. From the sizes given (0.4, 0.6, 0.4, 0.5, 0.3, 0.4, 0.6, 0.5, 0.3), the frequency of each size is:
Therefore, the mode is 0.4.
Step 2
Answer
The median is the middle value of a sorted dataset. First, sort the sizes: 0.3, 0.3, 0.4, 0.4, 0.4, 0.5, 0.5, 0.6, 0.6.
There are 9 values (an odd number), so the median is the value in the 5th position, which is 0.4.
