Friday. The day after Thanksgiving, 1950.
My sister and I are 3 years and 3 days apart, and both of us were born on a Saturday. I was born a couple weeks early, she a few days late, as she was supposed to actually be born on my birthday.
Planned deliveries have certainly created a distinct profile in more recent years, but presumably there were fewer of those back when many Dopers were born.

Thursday.
I have far to go, I guess.
Anyone care to do a significance test or such on Mondays in our sample?
Anyone else care to proffer a hypothesis to explain it?
Ok according to Chi-square Calculator
IF I’VE DONE EVERYTHING CORRECTLY INCLUDING NOT ONLY DATA ENTRY BUT ALSO SELECTING THE APPROPRIATE TEST TO DO ETC
P value and statistical significance:
Chi squared equals 10.843 with 6 degrees of freedom.
The two-tailed P value equals 0.0933
By conventional criteria, this difference is considered to be not quite statistically significant.
In other words if you were happy to take a 90% chance of there being a statistical difference, then there would be one. But we cannot say it’s statistically significant at 95% or higher confidence.
This was done when there were 249 non-other answers.
(Of course there don’t have to be more births on Monday for this phenomena to exist. It could be that doctors are all hungover on Monday mornings! :D)
