Answer:
median = 535
mode = 540
mean = 538.75
Step-by-step explanation:
To find the median, place the scores in order from smallest to largest, then find the middle score:
390, 460, 480, 480, 500, 510, 520, 530, 540, 540, 540, 580, 620, 630, 650, 650
As there is an even number of scores (16), the median is the average (mean) of the two middle scores (highlighed above).
Therefore, the median is 535
The mode is the number that appears the most.
Therefore, the mode is 540.
The mean is the total of the scores divided by how many scores there are.
Mean = (390 + 460 + 480 + 480 + 500 + 510 + 520 + 530 + 540 + 540 + 540 + 580 + 620 + 630 + 650 + 650) ÷ 16
⇒ Mean is 538.75
