America Vs Japanese Math Test Scores

The chart below shows the different math test scores throughout the American and Japanese people. According to the chart, the Japanese test scores are negative skewed and the American test score are positive skewed. I would say out of the two the Japanese scores are Leptokurtic and Americans test scores are Platykurtic. Looking at the graph the American's most concentrated distribution is between its 59% and 100%, with the Japanese scores you can see that it is pretty evenly distributed.
