Let's approach this step-by-step:
First, let's order these numbers from least to greatest:
386, 428, 440, 472, 510
Mean:
The mean is the average of all numbers.
Sum: 386 + 428 + 440 + 472 + 510 = 2236
Count: 5
Mean = 2236 ÷ 5 = 447.2
Median:
The median is the middle number when the numbers are in order.
With 5 numbers, the median is the 3rd number.
Median = 440
Mode:
The mode is the number that appears most frequently.
In this set, each number appears only once, so there is no mode.
Therefore:
Mean = 447.2
Median = 440
Mode = No mode (or the set is amodal)
