samanlagning

Samanlagning is a Swedish term for the process of combining separate items into a single whole. In statistics, data management and accounting, it refers to aggregating information or quantities to produce a summary or consolidated figure.

In statistics and data processing, sammanlagning includes operations such as summing values to obtain totals, computing averages or other descriptive statistics, and organizing data by categories. In database work, it corresponds to grouping and rollups that produce higher-level views from detailed records.

In accounting and finance, samanlagning refers to the consolidation of figures from different accounts, periods, or divisions into a single financial statement or report. It is distinct from sammanslagning, which denotes a corporate merger or acquisition in many contexts.

Applications and considerations: The technique aims to simplify data and reveal overall patterns, but it can obscure detail and must handle missing values, weighting, and anomalies carefully. When sharing aggregated data, privacy considerations may apply to prevent disclosure of small cell counts.

Examples: A retailer sums store-level sales to obtain total revenue; a statistical agency aggregates individual responses by region; a corporation consolidates subsidiary financials into a group-wide income statement.
