Generate an interactive quiz on matching data to a regression line
ResourceFunction["LinearRegressionDataQuiz"][] generates an interactive graphical quiz for users to specify points fit by a requested line. 
Check answer  automatically grades input with feedback 
Reset problem  resets the problem by removing all chosen points 
Next problem  randomly generates a new problem and internally saves the previous problem history 
Print report  prints a description of the problems that have been attempted so far, all guesses made and whether the last guess on each problem was correct 
Generate an interactive quiz on matching a specified regression line:
In[1]:= 

Out[1]= 

Clicking Check answer marks an attempt based on the number of points and the approximate linear fit of the chosen points. Correct attempts are marked with a green check mark:
In[2]:= 

Out[2]= 

If an attempt does not approximately meet the specified criteria, clicking Check answer marks the attempt as incorrect with a red x:
In[3]:= 

Out[3]= 

Clicking the Print report button returns a description of the problems that have been attempted so far, all guesses made and if the last guess on each problem was correct:
In[4]:= 

Out[4]= 

For uncorrelated points or a lowquality fit, the Pvalue is generally high and the tstatistic is low; similarly, for a set of points exhibiting large residuals, the coefficient of determination R^{2} is small:
In[5]:= 

Out[5]=
