Sample size and power calculations are available for one-sample and two-sample paired and independent designs, when the proposed analysis is construction of confidence intervals of a mean (one-sample) ...

This applet allows users to drag sliders to change the confidence level and sample size. The applet helps users visualize the meaning of the phrase "C% confidence," by showing that C% of the samples ...

Asymptotically, sample proportions from a multinomial distribution converge in distribution to a multivariate normal distribution with a singular negative product correlation structure. Based on this ...

Identify characteristics of “good” estimators and be able to compare competing estimators. Construct sound estimators using the techniques of maximum likelihood and method of moments estimation.

Are you feeling lucky? Most of us have been there: our hands are shaking; the perspiration thick on our brows. We slowly peel back the envelope to reveal the exam mark that will decide our future.

Explain the behaviour of a confidence interval over repeated independent sampling and how this is linked to the interpretation of a confidence interval as "providing a range of values which we are XX% ...
