Find the median and the mode of this data set:25,31,28,25,21,21,32,25,32. a 21,25 b 25,32 c 21,32 d 25,25?

Question

Does anyone know the correct answer???

Answer 1

The median would be the number in the middle if they're arranged in order. In this case there's nine numbers and if we rearrange them it's 21,21,25,25,25,28,31,32,32. The number in the middle (fifth) is 25.

The mode is the number that appears most often. Again, looking at the ordered sequence 25 appears most often (thrice).

The answer to the problem is (d).

Answer 2

Put the numbers in order - the MEDIAN is the one in the middle. The MODE is the score that occurs the most. You can get the answer from there.
