I am an professional statistician and researcher with major in advanced statistics and SPSS at postgraduate level. I have assisted 8 PhD (another is on going, two on bio-statistics) and many MS research projects as well as worked for 2 Australian Business firms, my responsibilities were, to organize data from various sources (i.e. Survey monkey, mostly survey data), Make them usable to analysis in SPSS, Excel or STATA and other analytic software, perform several analysis [i.e. Frequency distribution, Graphical representation (i.e. Pie, bar, dynamic chart) Descriptive statistics (i.e. Mean, median, mode, Std), Hypothesis testing (Chi test, T-test), Regression (linear, logistic), Correlations (bi-variate, multivariate) and so forth]. I can perform any statistical analysis and can also help to find proper way to do them. Would also interpret the results as necessary. Regarding your project my experience meets 100%, as i did these kind of control and treatment analysis, to find correlation and significant difference based on different hypotheses. For your project we may need to check correlation and analysis of t-test or U-test to find p-value (level of significance). Anyway, i can do this job easily and i also have international publications for statistical works. the point i am making, i am a pro data analyzer in SPSS and I can deliver you the best (check my profile feedback for statistics and SPSS-data analysis). Hope for a discussion, thanks in advance. Regards, Labib
