Friday, January 27, 2012

We began with this opener (pdf).

We then learned about Stem-and-Leaf Plots and Histograms (lesson, pdf).

Your homework for Monday is:
  1. Prepare for the Measures of Central Tendency and Dispersion Assessment. Please study.

  2. Review your notes on box-and-whiskers, stem-and-leaf, and histograms.

  3. Apple released their latest quarterly results this week and they were rather impressive. Here are just some of the numbers:
    It sold 37.04 million iPhones – its flagship product – and 15.43 million iPad tablets, doubling from a year earlier and easily outpacing already heightened expectations for a strong holiday season. That helped swell its warchest of cash and securities to almost $100 billion – more than enough to plug December’s U.S. budget deficit and level with California’s 2012/13 spending plan.
    Please write each of those big numbers in scientific notation.
