It features a detailed statistical breakdown relating student raw scores to percentile rankings, enabling educators and students to evaluate performance against the 1991 cohort data. The report includes essential psychometric indicators, such as the mean score of 23.9, the median score of 22.5, the standard deviation, and the KR-21 reliability coefficient of 0.86, offering a comprehensive assessment of the exam's validity and distribution. This material serves as a standard reference for academic testing and performance benchmarking within university-level chemistry programs, specifically designed to help instructors analyze test results and interpret student achievement levels effectively and accurately.",{"@graph":69,"@context":122},[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/inorganic-chemistry-form-1991-composite-norms/331730/",{"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/inorganic-chemistry-form-1991-composite-norms/331730.png","ImageObject",300,407,{"name":92,"@type":93},"Caleb Sterling","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-28","2026-09-21",true,{"@type":102,"interactionType":103,"userInteractionCount":52},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What was the mean score for the 1991 Inorganic Chemistry exam?","Question",{"text":112,"@type":113},"The mean score for the 1991 examination was 23.9.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What is the KR-21 reliability coefficient reported for this exam?",{"text":117,"@type":113},"The KR-21 reliability coefficient is 0.86, indicating the internal consistency of the test results.",{"name":119,"@type":110,"acceptedAnswer":120},"What is the minimum score required to reach the 90th percentile?",{"text":121,"@type":113},"According to the composite norms, a score of 37 corresponds to the 90th percentile.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},331730,1790118991,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":19,"category_name":20,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":52,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":8,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":143,"read_time":81,"preview_page_count":4},962084925290,"https://ap-avatar.wpscdn.com/davatar_085a072bc5b1113ac321206ff7593b45","| American Chemical Society Division of Chemical Education\u003Cbr>Composite Norms Inorganic Chemistry Form 1991 |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- |\n| Score | Percentile | Score | Percentile | Score | Percentile |\n| 60 | 100 | 40 | 93 | 20 | 38 |\n| 59 | 100 | 39 | 92 | 19 | 34 |\n| 58 | 100 | 38 | 91 | 18 | 31 |\n| 57 | 100 | 37 | 90 | 17 | 26 |\n| 56 | 100 | 36 | 89 | 16 | 21 |\n| 55 | 100 | 35 | 87 | 15 | 17 |\n| 54 | 100 | 34 | 85 | 14 | 14 |\n| 53 | 100 | 33 | 83 | 13 | 12 |\n| 52 | 100 | 32 | 80 | 12 | 9 |\n| 51 | 100 | 31 | 77 | 11 | 6 |\n| 50 | 100 | 30 | 74 | 10 | 4 |\n| 49 | 99 | 29 | 72 | 9 | 2 |\n| 48 | 99 | 28 | 69 | 8 | 1 |\n| 47 | 98 | 27 | 68 | 7 | 1 |\n| 46 | 97 | 26 | 65 | 6 | 1 |\n| 45 | 97 | 25 | 60 | 5 | 0 |\n| 44 | 96 | 24 | 55 | 4 | 0 |\n| 43 | 95 | 23 | 52 | 3 | 0 |\n| 42 | 95 | 22 | 48 | 2 | 0 |\n| 41 | 94 | 21 | 44 | 1 | 0 |\n\nMean Std deviation Median KR-21 rel Std error/meas  \n23.9  \n9.52 22.5 0.86  \n3.62","cbCaiqDKq6daqZXK","https://ap.wps.com/l/cbCaiqDKq6daqZXK","pdf",64705,"English","# Score-Percentile Mapping\n## Statistical Overview","[{\"question\":\"What was the mean score for the 1991 Inorganic Chemistry exam?\",\"answer\":\"The mean score for the 1991 examination was 23.9.\"},{\"question\":\"What is the KR-21 reliability coefficient reported for this exam?\",\"answer\":\"The KR-21 reliability coefficient is 0.86, indicating the internal consistency of the test results.\"},{\"question\":\"What is the minimum score required to reach the 90th percentile?\",\"answer\":\"According to the composite norms, a score of 37 corresponds to the 90th percentile.\"}]","Inorganic Chemistry Form 1991 - Composite Norms | PDF",1789994912]
