—-------------------------- NOTA (score)
Im using Thunkable.
This data is from Thunkable.
The people rating there, and the data (ID, LOCAL, DATE, TURN, SCROE) goes to Airtable, like the table that I posted.
Okay, I understand now. You can either loop through the dates in Thunkable and sum the scores for each date that is the same or you can use a custom view/filter in Airtable to retrieve only the scores for a specific day. I think I might try to do all of this in Airtable and have the spreadsheet calculate the averages for each day. And then pull the values into Thunkable.
The main problem with that approach is that you can’t use a variable to dynamically reference an Airtable view. So I’m not sure how to connect each new day with Thunkable. Maybe it all has to happen in a single view. Probably.
But I need to use this dynamically. For each place will have a different average. I will use it to TRY to predict the next wave score.
I want to compare the average with some surf forecast data (windy, swell…).
Of course that I don’t know if its possible.
It sounds like you need to figure out the algorithm for all of these averages and predictions. Or maybe you already know it. But you’ll need to explain it in lots of detail so that someone here can help you figure out the blocks you will need in Thunkable.
First of all, you need another column in your table to keep that average NOTE.
You just can’t replace NOTE with average, as a user can further give a NOTE and average will be re-calculate after that.
This being said, lets think further.
I think about this algorithm this way: average will be given by sum of all notes of records that matches condition / number of those records.
So you need to loop through all record, check if matches condition, sum the notes and divide to its number.
It might be some further speed or optimized improvements for this, I just want it to give you some fast guidance on how to think for your problem.
Notice This is for a local table. As I don’t use Airtable i don’t know if there is some automation that will help you skip some of steps from here.
Thanks! Lets do it!
Ok. Let me know if you succeeded
It’s very hard.
It’s almost work. I don’t know if the average is right, maybe it’s working just for last 2 scores.
And the average happen slow, I really don’t know when.
That’s the project: Thunkable
I don’t know whats the problem.
You may easily manually check. Using average as integer when it comes to pretty same NOTES will round the result. You get much more accurate average value if you will use 2 decimals instead.
Using LocalDB as source of DVL - Thunkable Discuss - Community
and you will see that I’m complaining about the speed when using local tables too. For Airtable, GoogleSheets is even worst when it comes to do calculations with large data…
@domhnallohanlon promised me that will provide an answer so I’m confident
Maybe in your case you can implement some trick that @muneer taught us, about making another filtered sheets from original sheets in Airtable, then use that for DVL. This way you can sum directly an entire column from filtered and speed up the app.
Do you think is possible do the average if I send the data to Firebase?
Can you share your Airtable table so I can build the blocks required for the average and test it with the data?
Example of average formula in thunkable:
Variable added_number has the total of all the values you want to get the average of. Variable numofquest’s value is the number of numbers you previously added.
2 + 8 = 10
10 / 2 = 5
In this example, 2 and 8 are the two values I want to get the average of, and 5 is the average number.
Hope this helps!
Thank you but the issue is about grouping not just averaging
I made a quick project for your review.
The idea is to create a group. I created it by looping through the records and filling a list. Ideally you want to create the grouping inside Airtable.
See this example
I’m here making a column as a group which adds two fields together within Airtable by doing this
Now that I do not have access to your table to add a column, I did the grouping in Thunkable. Once the grouping is done, I then filled the list with group names from the list without repeating the names. (I made the names from the 3 columns with “||” as separator.
When you click on the item in the list, I loop through the main list to count the entries and total the scores and in the end I display the average.
Hope this helps.
I tested just for today, then I’ll se in other “local” and days.
Thanks very much for all!
Maybe I come back here :]
