For those of you who were not here today we have a substitute teacher. Mr.Max has left us some instructions or STUFF to do.

1. The AM is set for us to do practices

2. Some people such as myself got to do there AM Wiki help thing to do. It needs to be done for tomorrow.

3. We got to google and make notes on two definitions( Confidence Iinterval and Margin of Error)

I thought it would be nice of me to post the definitions for you courtesy of Wikipedia.

Confidence interval

From Wikipedia, the free encyclopedia

In statistics, a confidence interval (CI) is a particular kind of interval estimate of a population parameter and is used to indicate the reliability of an estimate. It is an interval that frequently includes the parameter of interest, if the experiment is repeated. How frequently the interval contains the parameter is determined by the confidence level or confidence coefficient. Confidence intervals are used in frequentist statistics; the equivalent in Bayesian statistics is the credible interval.

Margin of error

From Wikipedia, the free encyclopedia

The margin of error is a statistic expressing the amount of random sampling error in a survey's results. The larger the margin of error, the less faith one should have that the poll's reported results are close to the "true" figures; that is, the figures for the whole population. Margin of error occurs whenever a population is incompletely sampled.



I would normally post my opinion on the definitions but I think I will save the good meaning full discussion for Mr.Max to tell.
