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 ...

In this module, we will generalize the lessons of Module 4 so that we can develop confidence intervals for other quantities of interest beyond the distribution mean and for other distributions ...

Confidence intervals are computed from a random sample and therefore they are also random. The long run behavior of a 95% confidence interval is such that we’d expect 95% of the confidence intervals ...

If someone claims the parameter is equal to 62, and 62 is not within your confidence interval, then this claim is suspect. Here's another distinction between what a p-value and CI tells us: a p-value ...

ANOVA will tell you whether there is a statistically significant difference in the population means of three or more groups ...

For example, a time series with one observation each month has a monthly sampling frequency or monthly periodicity and so is called a monthly time series. In the SAS System, data periodicity is ...

For instance, with a 90% confidence interval, analysts can assert that the true percentage change will likely fall between the lower and upper bounds stated. These intervals account for sampling ...
