The variance is a basic term in statistics. For example,the symbol S^2 is used for the sample variance,V is for unbiased variance,andσ^2 is for population variance. The authors of the textbook use the symbols for sample variance and unbiased variance according to their own point of view. However,in the textbooks of basic science,such as physics and chemistry,the symbols are used in a unified way. So comparing with it,the use of symbols in the field of statistics is really peculiar. To examine the variation in the actual,we investigated about 650 books of a collection of privately owned and Sapporo Gakuin University library. In addition,and as a consideration for the beginners,we present a method which should lead them to obtain the“variance”in an easy and right way.","subitem_description_type":"Abstract"}]},"item_4_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Bulletin","subitem_description_type":"Other"}]},"item_4_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"情報科学","subitem_description_type":"Other"},{"subitem_description":"Information Science","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"2379","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NAKAMURA, Nagatomo"}]},{"nameIdentifiers":[{"nameIdentifier":"2380","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HANAOKA, Shigetoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"2381","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TSUCHIYA, Takahiro"}]}]},"item_4_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"札幌学院大学総合研究所"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2188-4897","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中村, 永友"}],"nameIdentifiers":[{"nameIdentifier":"2376","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"花岡, 重利"}],"nameIdentifiers":[{"nameIdentifier":"2377","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"土屋, 高宏"}],"nameIdentifiers":[{"nameIdentifier":"2378","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-07"}],"displaytype":"detail","filename":"SK-1-001.pdf","filesize":[{"value":"491.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SK-1-001.pdf","url":"https://sgul.repo.nii.ac.jp/record/1807/files/SK-1-001.pdf"},"version_id":"f778b34b-0ff6-4e6c-97da-cdbc39226051"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"標本分散","subitem_subject_scheme":"Other"},{"subitem_subject":"不偏分散","subitem_subject_scheme":"Other"},{"subitem_subject":"母分散","subitem_subject_scheme":"Other"},{"subitem_subject":"Sample Variance","subitem_subject_scheme":"Other"},{"subitem_subject":"Unbiased Variance","subitem_subject_scheme":"Other"},{"subitem_subject":"Population Variance","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"統計学テキストの「分散」の表記に関する調査","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"統計学テキストの「分散」の表記に関する調査"}]},"item_type_id":"4","owner":"3","path":["153"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-05-25"},"publish_date":"2015-05-25","publish_status":"0","recid":"1807","relation_version_is_last":true,"title":["統計学テキストの「分散」の表記に関する調査"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-27T03:58:41.755929+00:00"}
