Q

How did your remember what sign to use

A

gReateR
If it has an r in its name then is greater than or equal to sign ( apart from the r in wilcoxon signed ranks )

Q

How do you do the binomial sign test

A

1: data is categorised into a table of results
2: assign a sign to the different flows of direction and then write the sign for each participant (yes—> no= + no—>yes = - )
3: calculate the total for each sign
4: the smallest of the two totals becomes the observed value
5: find the critical value when p<_0.05 and n=__
6: write conclusion/significance statement

Q

How do you do a wilcoxon signed ranks

A

1:calculate the difference between each individual rating for each condition
2:then rank the differences
3:then calculate the observed value by summing the ranks of the least frequent sign
4:then find the critical value at p<_ 0.05 and n=__
5: see if results are significant

3:square each difference
4:add up all the squares
5:find the value for n
6:put all into equation where Ed2 =step 4
