The document outlines key learning objectives, such as reading scales, plotting data, and calculating statistical averages like the mean, median, and mode. It offers detailed instructions on interpreting proportions in pie charts based on fixed ratios and frequency, while also emphasizing data analysis skills essential for solving complex statistical problems.",{"@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/year-8-unit-12-statistical-diagrams/665370/",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/year-8-unit-12-statistical-diagrams/665370.png","ImageObject",300,407,{"name":42,"@type":43},"Mafia Boss","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-10-29",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",5,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is a pie chart?","Question",{"text":63,"@type":64},"A pie chart is a chart that uses sectors to illustrate proportions of a total dataset.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"How do you calculate the value of a single degree in a pie chart?",{"text":68,"@type":64},"You calculate it by dividing a known frequency value by its corresponding angle in degrees;
