The t-test results indicate a significant difference between the groups, with very low p-values for both one-sided and two-sided tests, suggesting the assumed variances do not significantly impact the outcome. Descriptive statistics reveal that the experimental group achieved a higher mean score (70.32) compared to the control group (45.86) in the post-test, with both groups having a range of 63. Further analysis of numeracy ability indicators shows the experimental group consistently outperformed the control group across several indicators, including analyzing information related to building space, solving everyday math problems, and interpreting analytical results for predictions and decision-making. The experimental group achieved significantly higher percentage scores in these areas, highlighting the effectiveness of the intervention or teaching method used in the experiment.",{"@graph":69,"@context":123},[70,84,106],{"@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":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/t-test-for-equality-of-means-and-numeracy-ability-indicators/180229/",{"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/t-test-for-equality-of-means-and-numeracy-ability-indicators/180229.png","ImageObject",300,407,{"name":92,"@type":93},"Hazel","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-17","2026-09-02",true,{"@type":102,"interactionType":103,"userInteractionCount":105},"InteractionCounter",{"@type":104},"ViewAction",12,{"@type":107,"mainEntity":108},"FAQPage",[109,115,119],{"name":110,"@type":111,"acceptedAnswer":112},"What was the outcome of the t-test for equality of means?","Question",{"text":113,"@type":114},"The t-test indicated a statistically significant difference between the groups, with p-values of .001 for both one-sided and two-sided tests, suggesting the experimental intervention was effective.","Answer",{"name":116,"@type":111,"acceptedAnswer":117},"How did the experimental group perform compared to the control group in the post-test?",{"text":118,"@type":114},"The experimental group achieved a higher mean post-test score of 70.32, while the control group scored an average of 45.86.",{"name":120,"@type":111,"acceptedAnswer":121},"Which numeracy ability indicator showed the largest performance gap between the groups?",{"text":122,"@type":114},"The largest percentage gap was observed in 'Using a wide variety of numbers or symbols related to basic mathematics in solving everyday life problems,' where the experimental group scored 60% and the control group scored 27%.","https://schema.org",{"og:url":83,"og:type":125,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":127,"canonical":83},"index,follow",{"doc_id":129,"site_id":62},180229,1788339991,{"code":4,"msg":5,"data":132},{"doc_id":129,"user_id":133,"nickname":92,"user_avatar":134,"doc_module":4,"category_id":39,"category_name":40,"doc_title":65,"doc_description":67,"doc_content":135,"file_id":136,"file_url":137,"file_type":138,"file_size":139,"view_count":105,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":140,"language":141,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":142,"faqs":143,"seo_title":144,"seo_description":67,"update_tm":130,"read_time":145,"preview_page_count":4},137441390410,"https://ap-avatar.wpscdn.com/avatar/2000252f4ab5702993?_k=1776741390130283984","|  |  | t-test for Equality of Means |  |  |  |\n| --- | --- | --- | --- | --- | --- |\n|  |  | T | Df | Significance |  |\n|  |  |  |  | One-Sided\u003Cbr>p | Two-Sided p |\n| Nilai\u003Cbr>siswa | Equal variances assumed | 4,914 | 54 | ,001 | ,001 |\n|  | Equal variances not assumed | 4,914 | 53,970 | ,001 | ,001 |\n\n\n| Descriptive Statistics |  |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- | --- |\n|  | N | Range | Min | Max | Mean | Std.
