Do you not need to do n-1 when you’re trying to find degrees of freedom on 3:43 so would it not be comparing 0.7 with 0.950 (n=4)?

@clarebiology2858 2 месяца назад

df = n-1 where n is the number of pairs

@@clarebiology2858can you elaborate please you’ve done 2 rankings doesnt that count as a pair?

@masoud1082 4 месяца назад

hi at 4:36 why is the rank 4.5 and not 4. Thanks again for the videos

@clarebiology2858 4 месяца назад

you only have two numbers are the same so you are sharing the rank 4 and 5 between two numbers. Therefore they both get 4.5 and the next number you start off at six. Hope that helps.👍

@masoud1082 4 месяца назад

So if the first rank has 2 or more of the same number e.g ranked 3 then if there is a number in rank 2 that is the same then it would be ranked 3.5

I’m a bit confused by your comment, watch the video again and hopefully it will make more sense 🤞
