Answer:
The central tendency that changes is the median.
Step-by-step explanation:
- The mean without number 4 is 28.
28/7 = 4
But if we add the 4, the mean would be 32.
32/8 = 4
The mean does not change.
- The mode also does not change because the number that appears most frequently is 3.
- And the range does not change either since the range is the subtraction of the largest number with the smallest, in this case:
8 - 2 = 6
- On the other hand, the median is the middle number, without 4 the median would be 3, but with 4 the median would be 4 + 4/2, which is the same 4.
