 0     math_lower_bound grapher/oecd/2023-12-06/pisa/pisa_math_boys_girls#math_lower_bound   2 major           Assessed through the PISA mathematics scale, which measures how well someone can use math to solve everyday problems and understand the role of math in the real world. Represents the lower bound of the average mathematics score for 15-year-old on the PISA scale. Initially, the average PISA score across subjects and all OECD countries was at 500 with a standard deviation of 100, so that most students scored between 400 and 600. Scores in later cycles were calibrated to remain comparable to this baseline. 
[]
 Calculated as the average mathematics score minus 1.96 times the standard error, representing the lower bounds of a 95% confidence interval.       float
