An R Introduction to Statistics

Elementary Statistics with R

Tutorials on elementary statistics with R.

Sampling Size of Population Mean

A tutorial on computing the sampling size for the desired margin of error of population mean estimate at given confidence level.

Interval Estimate of Population Mean with Unknown Variance

A tutorial on computing the interval estimate of population mean at given confidence level. The variance of the population is assumed to be unknown.

Interval Estimate of Population Mean with Known Variance

A tutorial on computing the interval estimate of population mean at given confidence level. The variance of the population is assumed to be known.

Point Estimate of Population Mean

A tutorial on computing the point estimate of population mean from a simple random sample.

Interval Estimation

fractal-01h It is a common requirement to efficiently estimate population parameters based on simple random sample data. In the R tutorials of this section, we demonstrate how to compute the estimates. The steps are to be illustrated with a built-in data frame named survey. It is the outcome of a Statistics student survey in an Australian university.
