The outliers are 1, 6 and 9 while the mean is 3.5 and the range is 8
How to Interpret a Dot Plot?
1) From the given dot plot, we can say that the outliers are 1, 6 and 9. This is because these numbers are far away from the general number of people in each household.
2) The mean is;
[(1 * 1) + (2 * 4) + (5 * 3) + (4 * 4) + (5 * 4) + (1 * 9)]/20 = 3.5
3) The range is the difference between the highest number and the lowest number. Thus;
Range = 9 - 1
Range = 8
