Which of these variables are independent and which variables are dependent, and what level of measurement were used, nominal,ordinal, interval and and or nominal for these variables?

Answer 1

Age, duration of illness, objective being eating, self vomiting, eating concern, weight concern, shape concern, restraint, IIP 32 total, EDEQ global score, hard to be sociable and RSES total are the independent variables whereas BMI, anxiety and depression are the depend variables.

The variables whose mean, range and standard deviation are given in the tables are the quantitative continues variables and the measurable scales of these variables are ratio scale. The variables are in ratio scale as age, BMI, eating concern, weight concern, shape concern, restraint, duration of illness are the ratio scale where as the variables which has score, total score or total are the interval scale.

The varoables whose percentages are given, categorical or qualitavie variables and BMI < 18.5, objective being eating present, self induced vomiting present, are the nominal scale categorical variables.
