| Chi square conditions | nominal and independent |
| Binomial (nominal) | nominal and repeated |
| Man whitney | ordinal/interval and independent |
| Wilcoxon | repeated and ordinal / interval |
| spearmans's | relationships (speared heart= relationships) |
| Calculating Chi square | - add total of rows for each column
- row tot x column tot / overall tot = expected frequency
- add your data to your equation
-use number for critical value table by no of df by doing number of row/s column -1 times each other
SIGNIFICANT = GREATER THAN |
| Binomial sign test | - label the flow of direction + or - (yes to no = +)
- count the no of + or -'s
-the smallest of these scores is calculated value
- the critcal value is the no of directions
- SIGNIFICANT = LESS THAN |
| Manwhitney (multi) | - rank all columns together (MULTIPLE RANKNG)
- add up the ranks for each column
-use the formula for which ever column has the smallest ranking
- significant = LESS THAN |
| Wilcoxon | - work out the differences between the columns by takinf second column - first column
- rank the order of differences ignoring the sign
-count how many - or +
- least frequent sign = add up the ranks = observed value
critical value = no of differences
significant = LESS THAN |
| spearmans s= seperate | rank separately/ individual
find differences between ranks
square the differences applt to formula
significance = greater than |
