variance: Variance Function

Description

This function calculates the variance of a numbers vector.

Usage

variance(x = NULL, learn = FALSE, interactive = FALSE)

Value

The variance of the vector (for non-interactive mode)

Arguments

x

Optional numeric vector (not needed for interactive mode)

learn

Logical, if TRUE shows step-by-step explanation

interactive

Logical, if TRUE enables interactive practice mode

Examples

data <- c(10,4,5,7,3,4,1)

# Simple calculation
variance(data)

# Learning mode
variance(data, learn = TRUE)

# Interactive mode
if(interactive()){
variance(interactive = TRUE)
}
