Professor, I found some people count parity and data bits position from left

Some people did from right. is it related with big and small Edina? 

e.g binary code has 0111 of 7 digit value

P : parity bit

D : data bit

Hamming code from left :   000 1111

position from left to right

P1

P2

D3

P4

D5

D6

D7

Hamming code from right : 1111 000

position from right to left

D7

D6

D5

P4

D3

P2

P1

What is right answer ? is it both correct?
