I'm going to try and make this as least confusing as possible, I apologize in advance if my attempt is a failure.
I work in education and am trying to create a predictive analysis document that will tell us how many class sections we will need to offer in a given semester.
I pulled data from the past five years and consolidated it into a pivot chart. I set the pivot chart to combine all courses with a common Subject, Course Title and Catalog Number (See image below for more detail), and output 3 different columns of values based on what we need.
The problem I am facing now is with curriculum changes throughout the years. There are some courses within the list that are no longer being offered and a new course with a new Course Title, Subject and Catalog Number that can now be substituted for the previously needed course. Since the data has been pulled into one pivot chart, both the old curriculum courses and the new curriculum courses are in one list.
I would like to somehow create a relationship between the old curriculum courses and the new curriculum courses. If possible I would like the names of the courses to remain separate, but the values of the old and new to be averaged out together in their respective rows.
In a new page, I plan on putting an easy to use form where the user can select a course subject and name, enter in some other necessary data and the document will output the amount of course sections needed.
Does anyone know of a way to make a relationship between two cells and have other cells effected by this relationship?
Thanks so much!

I've used Kahoot in the classroom and have several excel files with scores from quizzes.
Students attended quizzes by using unique IDs. In each file, scores are visible for each ID (but ordered by success on each quiz). There are also some students missing or stating wrong IDs (I'll ignore it).
Now I would like to accumulate all scores for all student IDs in one sheet and summarize them by Student ID.
How can I do that most efficiently?
Any pointer or advice is appreciated.
Thanks,
B.
Here's a high level guide to getting what you want along with a sample in this file.
Step 1 - Combine Files to Sheet with Unified Columns
Objective
The goal here is to:
Combine all of your data from other files to single sheet
Merge the data to be in a single column for each field (i.e. Column A has ID, Column B has score).
No breaks in rows.
No formulas.
To illustrate, I made this fake list based loosely on your
description.
Method
You probably can do this manually, but a macro could also be used. If you expect to do this year over year, you might look into vba to open close files in a folder. However, since that wasn't part of question, you can do copy-paste (better yet make a kid do it!). Just make sure there's only one header for each column, and all of the data records align. Probably should do copy paste value if you have any formulas.
Step 2 - Show Summation
There's a couple ways this could be done. A pivot table is probably the most sensible because you could include each quiz as a column to see the total. You could also use a pivot table to do averages by student etc.
TO make a pivot table, I would recommend going on YouTube and they will do a better job of explaining than me.
On that same file I made as an example, I included some tabs to illustrate the power of pivot tables and a couple graphs.
Hope that helps. If you have specific technical questions on this, you might consider asking separately.
Wondering if anyone can help me, I am currently learning, SRSS Reports and have been tasked with a Pay & Display vehicle registration report, for staff and student carparks, to show if they are registered for P&D. I have the report laid out as a 3 table column; Name, Vehicle Number and Vehicle Registration. I have from the below code set out in my datasets the Vehicle Number and Vehicle Registrations pulling through, with a parameter to filter out if is staff or student pay and display. However I am having difficulty with pulling the Staff and Student names into one name column as they are through two different datasets. Can anyone be of help at all please? TIA
I don't see the code, but in general, to join between two different datasets you use LOOKUP.
LINK
https://learn.microsoft.com/en-us/sql/reporting-services/report-design/report-builder-functions-lookup-function?view=sql-server-2017
The basic format:
=LOOKUP
(
Fields!key column from the dataset assigned to the table.Value,
Fields!key column from the dataset you are matching to.Value,
Fields!column you want to bring back.Value,
"the name of the other dataset"
)
Warning: Performance can be pretty bad if they're big datasets. You might be better off creating a new dataset that already does this work in the database.
I have a database in Tableau from an Excel file. Every row in the database is one ticket (assigned to an Id of a customer) for a different theme park across two years.
The structure is like the following:
Every Id can buy tickets for different parks (or same park several times), also in different years.
What I am not able to do is flagging those customers who have been in the same park in two different years (in the example, customer 004 has been to the park a in 2016 and 2017).
How do I create this calculated field in Tableau?
(I managed to solve this in Excel with a sumproduct fucntion, but the database has more than 500k rows and after a while it crashes / plus I want to use a calculated field in case I update the excel file with a new park or a new year)
Ideally, the structure of the output I thought should be like the following (but I am open to different views, as long I get to the result): flag with 1 those customers who have visited the same park in two different years.
Create a calculated field called customer_park_years =
{ fixed [Customerid], [Park] : countd([year]) }
You can use that on the filter shelf to only include data for customer_park_years >= 2
Then you will be able to visualize only the data related to those customers visiting specific parks that they visited in multiple years. If you also want to then look at their behavior at other parks, you'll have to adjust your approach instead of just simply filtering out the other data. Changes depend on the details of your question.
But to answer your specific question, this should be an easy way to go.
Note that countd() can be slow for very large data sets, but it makes answering questions without reshaping your data easy, so its often a good tradeoff.
Try this !
IFNULL(str({fixed [Customerid],[Park]:IF sum(1)>1 then 1 ELSE 0 END}),'0')
I am trying to create a formula but with no luck for now.
My formula should work for the following situation:
I have a table that reflects data about trainings taken in one department.
As columns we have:
Region
Managers Names
Trainees Names
Training Details
Training Status
Status Comments
I need a formula that would allow me to say how many people I have trained (with no matter of what exactly training) while I filter any of the columns in the table (by Region, by Manager, by Training Status and etc. )
Important moment here is that when I filter I might have repetitive Trainees Names, but I want the final # of trained people to have included only unique values. I can’t get rid of duplicated Trainee Names in the table itself because it’s ok to have them there (for instance one person have one completed training and another that is currently ongoing and with that I have his/her name appearing twice in the “Trainees Names” column). All people in the table passes at least one training.
This is exactly what a PivotTable can do (and more) in Excel 2013. Put everything into FILTERS and Trainees Names into VALUES, as Distinct Count.
I have several documents which contain statistical data of performance of companies. There are about 60 different excel sheets representing different months and I want to collect data into one big table. Original tables looks something like this, but are bigger:
Each company takes two rows which represent their profit from the sales of the product and cost to manufacture the product.I need both of these numbers.
As I said, there are ~60 these tables and I want to extract information about Product2. I want to put everything into one table where columns would represent months and rows - profit and costs of each company. It could be easily done (I think) with INDEX function as all sheets are named similarly. The problem I faced is that at some periods of time other companies enter the market:
Some of them stay, some of them fail. I would like to collect information on all companies that exist today or ever existed, but newly found companies distort the list (in second picture we see, that company BA is in 4th row, not BB). As row of a company changes from time to time, using INDEX becomes problematic, because in some cases results of different companies get into one row. Adjusting them one by one seems very painful.
Maybe there is some quick and efficient method to solve such problem?
Any help or ideas would be appreciated.
One think you may want to try is linking the Excel spreadsheets as tables in Access. From there you can create a query that ties the tables together. As data changes in the spreadsheets, the query will reflect those changes.
