Here are shoAvn the number of errors for each child for each 

 line, and at the right a figure giving the line which may be con- 

 sidered as the estimated ability of the child in question. Thus, 

 Pupil 1 made 2 errors in line 5, 1 in line 6, 0 in line 7, etc., and his 

 estimated ability is line 10. At the bottom of the table the errors 

 for the several lines are totaled and the percentage of error for 

 each line is shown.
