NYC: Snow in April --- is it really abnormal?
Only summary data are available. I plotted the boxplots using five-number summaries provided. Some of the maximums are regarded as outliers by R.
R code: snow.R
In Spring 2005, I used a new example for w1111: snow falls in NYC. And that spring, we had record amount of snow. My students said that I jinxed it. :)
Well, today is absolutely not my fault.
