hi sir bea here, i had a question is at that at 8:13 the goals scored 0 count and you have to do 3-0 and not 3-1 but in the previous question the 0 was ignored?

[@corbettmaths]

So the range is the largest subtract the smallest, so it would be 3 - 0, giving you zero. I think you are maybe referring to the mean question and I did use the 0... I said in 9 matches they scored 0 goals, so that's 0 goals. Also I added 0 to the 10, 8 and 6 to get the grand total. I hope that helps

Hi Bea, did you have the time where I ignored the zero? Cheers
