calculateBasicStatistics: calculateBasicStatistics

Description

This function calculates the following statistcs for a set of data: length, mean, median, variance, standard error of the mean, and confidence interval bounds. The input data must be a vector of 2 or more numerical values.

Usage

calculateBasicStatistics(x, alpha = 0.05)

Value

A dataframe comprising the length, mean, variance, standard error and confidence limit bounds of the input data x.

Arguments

x

The data to be summarized

alpha

The probability level to be used when constructing the confidence interval bounds.
