In analyzing single system data, which statistical test would be appropriate to use if the dependent variable is dichotomous and nominal level (e.g., medication compliance/non- compliance) and the client is in compliance only 30 percent of days during a four week baseline (A) phase?
A) the mean effect size
B) the median test
C) the two-standard deviation method
D) the proportion/frequency method

The proportion/frequency method is appropriate for analyzing data with a dichotomous and nominal dependent variable. This method involves calculating the proportion or frequency of the behavior or outcome of interest (in this case, medication compliance) during the baseline phase and comparing it to the proportion or frequency during the intervention phase. In this scenario, the baseline proportion of compliance is 0.3 (30%), and this can be used as a baseline for comparison to see if the intervention results in an increase in compliance. Other tests such as the mean effect size, median test, and two-standard deviation method are not appropriate for dichotomous and nominal level data.
