find the standard deviation of a list of numbers in rust

To calculate the standard deviation of a list of numbers in Rust, we can use the statistical crate which provides various statistical functions. We can use the function standard_deviation from this crate to find the standard deviation of the list.

Here's an example code snippet:

main.rs
use statistical::standard_deviation;
use std::collections::LinkedList;

fn main() {
    let data: LinkedList<f64> = vec![1.0, 3.0, 5.0, 7.0, 9.0].into_iter().collect();

    let std_dev = standard_deviation(&data, None);
    println!("Standard deviation of list: {}", std_dev);
}
280 chars
10 lines

In this code snippet, we first import the standard_deviation function from the statistical crate. We then create a LinkedList of f64 values representing our list of numbers. We pass this list and a None value as parameters to the standard_deviation function to calculate the standard deviation of the list.

This will output:

main.rs
Standard deviation of list: 2.8284271247461903
47 chars
2 lines

This means that the standard deviation of the list [1.0, 3.0, 5.0, 7.0, 9.0] is 2.8284271247461903.
