Euclidean distance inquiry

[zahermoh]

Hi
Just want help in this, I have 11 inputs for person 1 and person 2. As following:

Person 1	Person 2
180	179.0
188.5	189.5
92.7	92.8
21.2	21.3
17.3	17.4
16.3	16.3
8.1	8.0
29.7	29
13.8	13.7
11.2	11.1
51.7	51.8

I want to find the Euclidean distance for those. The equation to use is attached in photo. Can anyone explain how to apply the equation in this case.? any input is appreciated.

What do those numbers represent - weight of those persons on different days - or height - or what?

What is the definition of "p" and "q" in the given formula?

Thanks Khan for replying. Theses parameters are for the following in same order
This is the full table
1-

Trait	Person 1	Person 2
1) Height (fig. 1)	180	179.0
2) Arm with (fig. 2)	188.5	189.5
3) Height seated (fig. 3)	92.7	92.8
4) Head width (fig. 4)	21.2	21.3
5) Head length (fig. 5)	17.3	17.4
6) Cheek width (fig. 6)	16.3	16.3
7) Right ear length (fig. 6)	8.1	8.0
8) Left foot length (fig. 7)	29.7	29
9) Third left finger length (fig. 8)	13.8	13.7
10) Small left finger length (fig. 8)	11.2	11.1
11) Left forearm length (fig. 9)	51.7	51.8

P1 will be height of person 1 and q1 will be the height of peron 2

Okay, so you need to sum all of the [math](p_i - q_i)^2[/math]'s.

Get out the calculator: (180 - 179)^2 + (188.5 - 189.5)^2 + ...

So then tell us what exactly is escaping you in the equation.

The process would be:

1. Calculate p_i - q_i for each parameter (or i)
   
   
2. Calculate [p_i - q_i]² for each parameter (or i)
   
   
3. Sum the numbers you got in 2.
   
   
4. Take square-root of the number you got in 3.
   
   And you are done.......

You're not going to do the calculations for the student? Wow!

Thank you it worked for me.

Thank you very much for the good explanation. you solved my query.
