Bar line chart below shows the percent of words spelled correctly by word length at the Scripps National Spelling Bee from 1996 to 2016. The bars indicate the share of words spelled correctly and the line shows the number of words. The most common word length is 9 letters. The data shows that longer words are not necessarily harder to spell. 3 letter words have appeared three times but only spelled correctly once. The two longest words, 19 and 21 letters in length, were both spelled correctly the one time each came up in competition.
This chart was built using Microsoft PowerPoint 2016 for Mac and the Aploris add-in.
