What do you need to know after a stats test?
When using one of these tests you end up with an observed value which you compare it to a critical value table.
You need to know :
1.) the level of significance ( default : 0.05)
2.) whether it is a one or two tailed hypothesis
3.) Number of participants (n) or degrees of Freedom ( for chi square it is no. of rows -1 x no. of columns -1)
