Presentation Transcript

  1. Normal Distribution • Calculate the Standard Score and calculate an observation from a standard score. • 68-95-99.7 rule • How StdDev and Mean relate to different normal curves • Kinds of things that will have different distributions: normal, uniform, bimodal, etc.

  2. Correlation/Regression • Identify patterns scatter plots (form, direction, strength) • Correlation – how to calculate it and what it means. • The relationship between correlation and causation • R2 – how to calculate it and what it tells us • LSR – when do we use it (and when can’t we use it), how to tell when it is doing a decent job representing the data, • Interpreting the slope and y-intercept • Using LSR to predict

  3. Calculator Stuff • Generating a list of random numbers using a random seed. • 123 -> rand thenRandInt(0, 1, 50) • Make a histogram/box plot or scatter plot • Stat Plot, pick your list, set your window • Find all the numbers for a 5-number summary • Stat then 1-var statistics • Calculate the mean and standard deviation • Same • Find the correlation, r2 and regression line • Stat then LinReg(ax+b)
