Before I read any chapters or reviewed any classroom notes I completed this tutorial and now I feed confident in the chapter and the basic concept of margin of error and confidence level. Thank you! |

Fantastic exposition! I'd been all over the intranets searching for a concise explanation of the concept of margin of error, and everywhere else I just found a bunch of confusing goobledygook. But yours is super clear with a great concrete example. Thanks for this!! |

"In other words, the margin of error means that James Bean could be favored by as much as 58 to 42 percent (55 + 3) or as low as 52 to 48 percent (55 - 3)-- a six percentage point spread (58-52 = 6). "
In the frst portion of the staement I understand where the 58 comes from (55+-3%). Where does the 42 come from? Ahhh the balance of scales. James gets 3% John looses 3% |

How the minus and plus margin were worded or connected in the last sentance.
to show how James Bean was favored over John Daniels. I understand the CI spread, but did not see the connection with plus and minus margins |
