Matching Graphs to Variables
Some people earn a lot of money each year, so there are some families with very large incomes relative to the rest of the population. Thus, if we were to collect family income data from a sample of Americans and then construct a histogram, we would expect the histogram to be skewed to the right. If we think about the type of data we would be likely to obtain, we can say something about the shape of the histogram without actually collecting the data. Can we do the same with other variables?
