Statistical Tests

Question 1

What is the rhyme to remember the stats test grid

Answer 1

Under red church’s nuns can’t backflip over men without shirts

Question 2

How did your remember what sign to use

Answer 2

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 )

Question 3

How do you do the binomial sign test

Answer 3

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

Question 4

How do you do a wilcoxon signed ranks

Answer 4

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

Question 5

How do you do a Mann Whitney U stats test

Answer 5

1:rank the scores across the 2 conditions
2:find the total of the ranks for both conditions
3:find the total number of participants for both conditions
4:then put the values into the equation
5:use the smaller of u1 and u2 as your observed value
6:find the critical value
7:observed <_ critical

Question 6

How do you do a spearman’s rho stats test

Answer 6

1:rank each condition separately
2:then calculate the difference between the ranks for each participant
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
7:find the critical value observed >_ critical
