Nuptial Age

Flowing Data has produced an interactive graphic showing the distribution of the age of marriage of Americans. Smoothed relative frequency distributions are shown for women (in green) and men (in orange) with selections possible by employment, education, race, or whether or not it is a first marriage. The data are from the American Community Survey marriages from 2009 to 2014. My guess is that similar frequency distributions from earlier decades would have modes that move more to the left towards younger ages for both women and me. What is the overall youngest median age of marriage for Americans? More data needed.

YADDA - Donut Bakery

Yet Another Door Distribution Again. This time on a bakery door just east of Cambridge, Maryland. Here we see a skewed frequency distribution of scratches, perhaps from keys, with greatest concentration around the door handle with progressively fewer scratches extending higher up the door. Many fewer scratches are below the door. Perhaps the handle is too low as customers handle their keys and hold or open the door, while also eating the delicious donuts the bakery sells.

Pipe Down

Here is a data comparison of the size of pipelines for fluids delivered or consumed in the US. But a Mayo, Maple Syrup, and Nail Polish mix sounds awful! From xkcd.
