Currently there are 28 children playing. Until a moment ago, 4 of those 28 werent there. To find out how many there were a moment ago, we have to exclude those 4 kids that just came — or subtract the number of kids that just came from the number of kids currently playing.

28-4=24

We can check: 24+4=28

Here is a data set: 5 10 10 10 15 100 after studying the data, the research realized that the value 100 was meant to be recorded
attashe74 [19]

Answer:

The mean and SD will change

The median is a better measure of the center since it will not change in this case

Step-by-step explanation:

Given that the value 100 was changed to 15, what will happen is that the value of the mean will decrease since there is a lower total value now. This will consequently decrease the value of the standard deviation too.

Yes, the median will be a better choice

This is because, by changing the value of 100 to 15, the value of the median stays the same and thus the previous information would not be changed if the median we used .
