How does a small outlier affect the data set?

A small outlier could affect the whole data set because it could reduce the mean, or make the average of the whole data set smaller.

An example would be the data set could be 1, 8, 9, 10

To find the mean you would add everything together then divide it by the number of numbers you just added together. The mean of this set would be 28/4 which equals 7. Now, if the outlier were -8 instead of 1, then the mean would be much different.

~Hope this helped!~

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

That they are numbers and related to each other.
