It provides a comprehensive percentile distribution corresponding to raw scores ranging from 1 to 70. Additionally, the report includes key psychometric statistics, such as the mean score of 39.22, a median of 38.54, a standard deviation of 12.16, a KR-21 reliability coefficient of 0.90, and a standard error of measurement of 3.92. These data points serve as an essential reference for evaluating student performance and comparing test results against established national benchmarks. The document is designed for educators and administrators involved in chemistry education assessment to accurately interpret student achievement based on statistically validated norms. By analyzing these percentiles, institutions can determine relative academic standing and identify trends in test outcomes for this particular standardized examination series.",{"@graph":69,"@context":126},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/organic-chemistry-composite-norms-2004-performance-analysis/331755/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/organic-chemistry-composite-norms-2004-performance-analysis/331755.png","ImageObject",300,407,{"name":92,"@type":93},"Gloria","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-26","2026-09-21",true,{"@type":102,"interactionType":103,"userInteractionCount":39},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118,122],{"name":109,"@type":110,"acceptedAnswer":111},"What is the mean score for the 2004 Organic Chemistry exam?","Question",{"text":112,"@type":113},"The mean score for the Organic Chemistry Form 2004 is 39.22.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What is the KR-21 reliability coefficient of this examination?",{"text":117,"@type":113},"The KR-21 reliability coefficient for the 2004 exam is 0.90.",{"name":119,"@type":110,"acceptedAnswer":120},"Which score corresponds to the 50th percentile in this dataset?",{"text":121,"@type":113},"A score of 39 corresponds to the 50th percentile.",{"name":123,"@type":110,"acceptedAnswer":124},"What is the standard deviation reported for this examination?",{"text":125,"@type":113},"The standard deviation for the 2004 Organic Chemistry examination is 12.16.","https://schema.org",{"og:url":83,"og:type":128,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":130,"canonical":83},"index,follow",{"doc_id":132,"site_id":62},331755,1790341019,{"code":4,"msg":5,"data":135},{"doc_id":132,"user_id":136,"nickname":92,"user_avatar":137,"doc_module":4,"category_id":19,"category_name":20,"doc_title":65,"doc_description":67,"doc_content":138,"file_id":139,"file_url":140,"file_type":141,"file_size":142,"view_count":39,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":8,"language":143,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":144,"faqs":145,"seo_title":146,"seo_description":67,"update_tm":147,"read_time":81,"preview_page_count":4},2336474459895,"https://ap-avatar.wpscdn.com/avatar/22000baeef7a5ed0655?x-image-process=image/resize,m_fixed,w_180,h_180&k=1786071322749376916","| American Chemical Society Division of Chemical Education\u003Cbr>Compostie Norms Organic Chemistry Form 2004 |  |  |\n| --- | --- | --- |\n| Score Percentile | Score Percentile | Score Percentile |\n| 70 100 | 46 69 | 22 8 |\n| 69 100 | 45 66 | 21 6 |\n| 68 100 | 44 64 | 20 5 |\n| 67 100 | 43 61 | 19 4 |\n| 66 99 | 42 58 | 18 2 |\n| 65 99 | 41 55 | 17 1 |\n| 64 98 | 40 53 | 16 1 |\n| 63 98 | 39 50 | 15 1 |\n| 62 97 | 38 48 | 14 0 |\n| 61 96 | 37 45 | 13 0 |\n| 60 95 | 36 42 | 12 0 |\n| 59 94 | 35 40 | 11 0 |\n| 58 93 | 34 37 | 10 0 |\n| 57 92 | 33 34 | 9 0 |\n| 56 90 | 32 32 | 8 0 |\n| 55 89 | 31 29 | 7 0 |\n| 54 87 | 30 26 | 6 0 |\n| 53 85 | 29 23 | 5 0 |\n| 52 83 | 28 21 | 4 0 |\n| 51 81 | 27 18 | 3 0 |\n| 50 79 | 26 16 | 2 0 |\n| 49 77 | 25 14 | 1 0 |\n| 48 74 | 24 12 |  |\n| 47 72 | 23 10 |  |\n\nMean Std deviation Median  \nKR-21 reliability Std error/meas  \n39.22 12.16 38.54  \n0.90 3.92","cbCaidWYgh8UceZN","https://ap.wps.com/l/cbCaidWYgh8UceZN","pdf",65741,"English","# Performance Analysis\n## Percentile Score Distribution\n## Statistical Data Summary","[{\"question\":\"What is the mean score for the 2004 Organic Chemistry exam?\",\"answer\":\"The mean score for the Organic Chemistry Form 2004 is 39.22.\"},{\"question\":\"What is the KR-21 reliability coefficient of this examination?\",\"answer\":\"The KR-21 reliability coefficient for the 2004 exam is 0.90.\"},{\"question\":\"Which score corresponds to the 50th percentile in this dataset?\",\"answer\":\"A score of 39 corresponds to the 50th percentile.\"},{\"question\":\"What is the standard deviation reported for this examination?\",\"answer\":\"The standard deviation for the 2004 Organic Chemistry examination is 12.16.\"}]","Organic Chemistry Composite Norms - 2004 - Performance Analysis | PDF",1789994997]
