# 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

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.

## Chi-squared Distribution

A tutorial on the Chi-squared distribution.

## Student t Distribution

A tutorial on the Student t distribution.

## Normal Distribution

A tutorial on the normal distribution.

## Exponential Distribution

A tutorial on the exponential distribution.

## Continuous Uniform Distribution

A tutorial on the continuous uniform probability distribution.
