What can we conclude from this limited data set?
1. Apparently, our parenting is such that we can produce and maintain near replicates (well, pseudoreplicates at any rate).
2. Despite actively refusing all bottles, cups and droppers, Baby Wily is no worse for the wear.
3. Older versions of MS Excel 2008 for Macs did not include an option for custom error bars. The standard error as calculated by Excel, was, in Jenni's words, "wonky."
4. Your conclusion here - leave your ideas in the comments.

1. Wouldn't it make a lot more sense to just plot the two points on the graph, one color for TJ and one for BW? Plotting it as a standard deviation just makes it a lot more confusing.
2. You call this geek-i-tude? You're using *Excel*. That's not very geeky. You should be using Topcat:

It allows you to go the extra light year and do full 3d plotting. And custom error bars are not a problem.
I could totally have plotted separate points - but what fun is that? Then, there's no calculating the mean, StDev or error. I decided to jump the shark, wear plaid with polka dots, eat pickles and ice cream.
Although separate points would emphasize the differences, the error bars show the near identity of the data. More interesting to see will be how long the linear extrapolation will hold. It would also be interesting to see where data from the parental gene pool falls on the line!

OK, Grandpa's comment is the only one that really hits the high geek-i-tude. Though it would be interesting to see that data for multiple generations, color coded by gender...
I would love to know how you calculate standard deviation with two data points. Can I see your equation. Or do you have a third child that you are not telling us about?
