Deliverable: Working Tableau workbook around data types and desirable contents Freelancer sought: Expert Tableau builder with understanding of statistics (will need some statistics calculations in report) Specific needs: 1) to create a type of "psychometric" view in Tableau. Sample data can be provided. Basically, each individual in the data needs to A) have a total score calculated, B) be categorized into a "performance group" like upper 20% or lower 20% based upon their score compared to all other individuals. Then each group's performance on various questions is displayed visually as in the image below. Each line would represent an answer choice. This is basically what is called a "distractor analysis" like here (see also Figure 1): [login to view URL] . Ideally this would be displayed with filters as shown in Figure 2, with the ability to compare two different data points. 2) I have need to convert specific answers into a "generic" type that can be exported if needed. For example, if the correct one is "quadratic formula", I need this recoded as "A" or "1" (A or 1 would always be the right answer. If there are two remaining incorrect ones (distractors), then I need it to assign a "B/2" and "C/3" to those choices. I have tried to do this, but I need someone to check this logic and see if there is an easier way to code this inside Tableau. 3) I have need to find three calculations inside Tableau that can be filtered as needed based on individual characteristics (e.g., region, exam language, etc). The first is the "difficulty", which is simply the % of people that get it correct. The last two of these values give an idea of the psychometric idea of "discrimination." The first is a point-biserial correlation, which is just like a correlation coefficient between a score (which would be a SUM of the correct indicators for each individual) and a specific item outcome (1/0 where 1 = right and 0 = wrong). This formula is shown in Figure 3. The last formula is just a subtraction of percentile ranks ... 73rd percentile minus 27th percentile (see Figure 4). Each of these numbers are statistics on the individual ITEMS. 4) Finally, I need to create overall summaries for the entire collection of items. This would include the average difficulty (% correct), an average for each of the 2 discriminations listed in #3, and something called a KR-20 metric. This KR-20 calculation in Excel is shown here: [login to view URL] . I need this to be in a type of "report card" as shown in Figure 5. All of these are aggregates of the total.

Hi Sir, I am an industrial engineer holding masters degree from Swedish Jönköping University. I am specialized in data analysis and discrete event simulation having more than 5 years experience in this field both as a freelancer and full-time employee. During my employment as a business consultant, I have analyzed huge amount of data in Excel and created appealing dashboards in Tableau to present them. Due to my strong background in industrial engineering and discrete event simulation modeling, I am also very familiar with statistical analysis. I have read the article you have shared the link for in the job description and I understand the first 2 steps of the job description and I can do it easy. I can also build a dashboard with filter options as shown in Figure 5 for the last step. However, I need some detailed explanation for the 3rd and 4th remaining steps. I would be glad to assist you in this project and I can start immediately, Kind regards, Tolgahan

If you need the solution on a permanent basis (one or more users in the group) and not Tableua as a must then my cloud based solution could be the right one for you. 1) Powerful OLAP based BI platform accepting data from different sources via ETL module (data adjustments). 2) Robust, secure, modular and fully scalable business modelling. 3) Business model adjustable to the end-user needs; multilingual – with pre-prepared BS, P&L, CF and KPIs. 4) Supporting all four stages of a business cycle: planning-reporting-analysing-adjusting – bigger/more complex the organisation, bigger our value added. 5) Pre-designed (e.g., “what if”) and on the fly analysis included. 6) Win and full mobility - iOS, Android. You can use it (1) inside our DB in cloud (under MS Azure); (2) more demanding business models can be set-up in their own DB in our cloud or (3) set up your own DB in your cloud (highest costs). Details and demonstration on request. Best way would be to show you in live web session via TV, Skype or similar. Let me know. @RMC
