Step 1

Calculate the Mode

96%

114 rated

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:

0.3 appears 2 times
0.4 appears 3 times
0.5 appears 2 times
0.6 appears 2 times

Therefore, the mode is 0.4.

Step 2

Calculate the Median

104 rated

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.

Step 3

Identify the Correct Statement

Answer

The determined mode (0.4) and median (0.4) match the option B: "The mode and the median size are both 0.4."
