		+	* (5) the relationship between bell curves and the normal distribution (bell curves are the density curves for normal distributions)
		+	* (6) Bell curves have a very specific shape that depends on only two parameters: mean and standard deviation
		+	* (7) knowing mean and standard deviation you can write down an exact mathematical formula for the bell curve
		+	* (8) If mean is mu and standard deviation is sigma, the unique normal distribution is denoted N(mu,sigma)
		+	* (9) mean, median, and mode of a density curve: for a bell curve these three things coincide at the peak
		+	* (10) at one standard deviation from the mean of a bell curve you will find the inflection points where the curve goes from smiling to frowning or vice-versa (remember: bell curve means normal distribution, this doesn't work for other distributions).
		+	* (11) Another property of a normal distribution: if you do a linear transformation and the old variable is normal, the new one is normal, too. If the new variable is normal then the old variable must have also been normal.
		+	* (12) The 68-95-99.7 Rule, the percentage of area falling one, two, or three standard deviations from the mean.
		+	* (13) Pseudo-random numbers, simulating pseudo-random number in StatCrunch,
		+	* (14) The concept of seed, including fixed seed and dynamic seed.
		+	* (15) Standardizing observations and the z-score.

-* Today I presented the 5 number summary and related box plot and modified box plot.  We also talked about standard deviation and transformations.  I handed out the last of the chapters written last summer in [[Media:The_Data_Professors_Guide_to_Basic_Statistics.pdf|The Data Professor's Guide to Basic Statistics]] to cover sampling and Bessel's correction.  Finally there was a discussion in class about density curves, however if you did not follow it, don't worry: it will make more sense after we cover probability.
