Exporting student entered data to create a class scatterpot

[Ryan_Brown]

Looking for some help here.

I’m trying to build an activity where students enter one point of data into a table on slide 1 (height, armspan). I want slide 2 to display a graph with all student values plotted in a scatterplot. I’m struggling with the CL language on this.

Any suggestions?

Calculating/Displaying Correlation Coefficient from Aggregated Data

I am trying to calculate and display the correlation coefficient and the line of best fit from aggregated data (students input their foot length and height and a class scatterplot is created). I keep getting that the info for the line of best fit and the correlation coefficient is undefined, even when data is actually collected from an assigned class (I understand why it would come up as undefined without the actual data collected but am stumped as to why it’s not working when the data is actual…

Populate a table embedded in a graph?

I’m wondering if it’s possible to take the graph layer points that I’m porting over from slide 3 to slide 4 and have them auto-populate a table within the graphing calculator section. OR if there’s an easier way to set up a regression equation and r-value from the scatterplot. Thanks!!

Thanks, I’ll check those out!

I believe you use aggregate then use a Graph Component and make a distribution (Scatter Plot, in this case). Then you can use .script to retrieve the aggregate values from slide one. This is just the idea… the links Daniel posted are probably much more informative.
