Putting it All Together

• Statistics 2126

Big Themes

• We can describe data with numbers
• We do EDA
• We do some sort of procedure to either make an
  estimate or determine if there was an effect
• These are two sides of the same coin

And Finally

• The whole thing relates to the CLT
• In fact, all of the procedures we have learned
  have to do with, at a deep level, the z
  distribution

HELP!

• Always start by listing what you know
• If you are not sure of what formula to use, find
  the one that contains all of the info you have
  and of course, one that will answer the question
