Hello.  
[EDIT w/ cleaner examples]

i am trying to return the average from 4 numbers. using this code  
 ![Screen Shot 2020-04-01 at 12.04.02 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/7/67229454c77a828628af52fae96113a0edae6d2f.png)

`<>Y values` is 4 numbers. 5,2,1,0 as seen here but i get a weird number

I also get this value returned when i divide the sum of list Yvalues by the length of list Yvalues

what’s going on here.  
am i doing something wrong?

This is the entire code. I insert a list of y values as is seen in the example above. the rest of the code should produce two data points. a start and end point for a trend line.

when i run the whole code, \<\>m and \<\>b return as NaN.

it’s funny but your y-values 5,2,1,0 without the commas is 5210 , which when divided by 4 becomes 1302.5  
you may have entered 5,2,1,0 as a text string and it got processed as 5210, maybe it should be built as a list of 4 numbers.  
just guessing.

I think you’re right.

I hadn’t even considered that.

We’re on a quest rn, but I’ll try to turn text into a list and report back
