Means, standard deviations and standard errors
... In this game, we had the luxury of results from several different samples, and could draw the sampling distribution. Usually we are not in this position: we have just one sample that we wish to use to estimate the mean of a larger population, which it represents. We can draw the frequency distributi ...

... Remind students of transformations in Algebra 2 or Precalculus – when you add a value to a function – it shifts that function. The same thing happens in Statistics. If a value is added to every observation, then the distribution shifts. This does not change the spread of the distribution, thus not c ...
