calculateBasicStatistics | R Documentation |
This function calculates the following statistics 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.
calculateBasicStatistics(x, alpha = 0.05)
x |
The data to be summarized |
alpha |
The probability level to be used when constructing the confidence interval bounds. |
A dataframe comprising the length, mean, variance, standard error and confidence limit bounds of the input data x.
