To do this you must access the Animator Component, I recommend taking these lessons:
https://unity3d.com/learn/tutorials/topics/animation

Here is the code to achieve it for you reference:

    private Animator _animator;
    public float Speed;

	void Start ()
	{
	    _animator = GetComponent<Animator>();
	}
	
	void Update ()
    {
        _animator.SetFloat("SpeedParam", Speed);
	}
