Famous quotes containing the word statistics:

    “July 4. Statistics show that we lose more fools on this day than in all the other days of the year put together. This proves, by the number left in stock, that one Fourth of July per year is now inadequate, the country has grown so.”
    —Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    “We ask for no statistics of the killed,
    For nothing political impinges on
    This single casualty, or all those gone,
    Missing or healing, sinking or dispersed,
    Hundreds of thousands counted, millions lost.”
    —Karl Shapiro (b. 1913)

    “O for a man who is a man, and, as my neighbor says, has a bone in his back which you cannot pass your hand through! Our statistics are at fault: the population has been returned too large. How many men are there to a square thousand miles in this country? Hardly one.”
    —Henry David Thoreau (1817–1862)
