I have faced one problem which is related to hypothesis testing in ranked questions ( 1 for lowest and 10 for highest). For this which test is more appropriate.
You can consider the scale that was used to measure the studied variable as an ordinal scale, which enable the use of nonparametric tests. Deciding on the appropriate test depends on the type of relation between the dependent and independent variables.
To compare the relationship between ranked variables from survey data, try multivariate analysis. Since I'm assuming the data are categorical, check out correspondence analysis!
