A study of Golden Retriever Lifespans
The mean lifespan for the entire dataset of 4201 Goldens is 11.5 years. The plot below
indicates the mean life span of those who died in a given year. The next plot shows the number
in the dataset who died each year. 80% of the death dates are known to the day. If only the
month is given  I assign the death date to the middle of that month. If only the death year is
stated I pick the middle of the that year for calculation purposes. (Oct 2011)
The following figure displays a histogram of  lifespans for the entire dataset.
