It presents detailed statistical data derived from the performance of 1155 students across 22 participating institutions. The report includes a comprehensive score-to-percentile conversion table, along with key psychometric indicators such as the mean score of 38.5, a standard deviation of 12.2, a median score of 37, a KR-21 reliability coefficient of 0.90, and a standard error of measurement of 3.93. The visual representation includes a distribution histogram showing student performance trends across various raw scores, offering educators and administrators a standardized benchmark for evaluating examination outcomes and student achievement in organic chemistry coursework.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/exam/","Exam",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/american-chemical-society-organic-chemistry-2017-composite-norms/331653/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/american-chemical-society-organic-chemistry-2017-composite-norms/331653.png","ImageObject",300,407,{"name":42,"@type":43},"Ophelia","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-23","2026-09-21",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",8,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What
