+## hashing
+
+### Instructions
+
+Given a list of integers (Vec<i32>) write three functions
+
+Write a function called `mean` that calculates the `mean` (the average value) of all the values in the list
+
+Write a function called `median` that calculates the `median` (for a sorted list is the value in the middle)
+
+Write a function called `mode` that calculates the mode (the value
+that appears more often)
+
+### Expected Functions
+
+```rust
+fn mean(list: &Vec<i32>) -> f64 {
+}
+
+fn median(list: &Vec<i32>) -> i32 {
+}
+
+fn mode(list: &Vec<i32>) -> i32 {
+}
+```
+
+### Usage
+
+Here is a program to test your function.
+
+```rust
+use hashing;
+
+fn main() {
+	println!("Hello, world!");
+	let v = vec![4, 7, 5, 2, 5, 1, 3];
+	println!("mean {}", hashing::mean(&v));
+	println!("median {}", hashing::median(&v));
+	println!("mode {}", hashing::mode(&v));
+}
+```
+
+And its output
+
+```console
+student@ubuntu:~/[[ROOT]]/test$ cargo run
+mean 3.857142857142857
+median 4
+mode 5
+student@ubuntu:~/[[ROOT]]/test$
+```
