Each problem presents a series of values with one unknown variable and requires learners to calculate the total sum using the given mean and the count of values, followed by subtraction to isolate the missing data. The worksheet includes a dedicated answer section that details the step-by-step methodology, specifically showing the multiplication of the mean by the number of values to find the actual total and comparing it against the sum of known values to solve for the missing integer, decimal, or negative number. This resource is designed to strengthen algebraic thinking and foundational statistical skills for students requiring supplementary practice in arithmetic averages.",{"@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/mean-missing-data-sheet-3-mathematics-practice-worksheet/636673/",{"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/mean-missing-data-sheet-3-mathematics-practice-worksheet/636673.png","ImageObject",300,407,{"name":92,"@type":93},"Mary Man","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-03","2026-10-22",true,{"@type":102,"interactionType":103,"userInteractionCount":29},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"How do you find a missing data point given the mean?","Question",{"text":112,"@type":113},"To find the missing data point, first multiply the mean by the total number of values in the set to determine the total sum.
