It contains two main sections: a student worksheet consisting of 18 mathematical problems, each featuring a set of numbers with one missing value and a specified mean; and a comprehensive answer key that details the step-by-step methodology for solving each problem. The exercises are designed to reinforce the algebraic relationship between the mean, the number of values in a set, and the total sum. By requiring users to first calculate the total sum by multiplying the mean by the count of values and then subtracting the sum of the known values, this worksheet helps learners develop a deeper understanding of statistical averages and basic arithmetic problem-solving techniques. The clarity of the tables makes it an ideal tool for self-study, classroom practice, or homeschooling environments, focusing on precision and logical thinking in mathematics.",{"@graph":14,"@context":72},[15,34,55],{"@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/mean-missing-data-worksheet-2/636672/",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/mean-missing-data-worksheet-2/636672.png","ImageObject",300,407,{"name":42,"@type":43},"Mary Man","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-10-22",true,{"@type":52,"interactionType":53,"userInteractionCount":33},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"How do you find a missing data point when the mean is known?","Question",{"text":62,"@type":63},"To find the missing data point, first multiply the mean by the number of values in the set to find the total sum.
