This article aims to examine strategic split-voting in mixed systems by analyzing the results of elections in three countries using mixed electoral systems—Germany, Hungary, and Lithuania—to further improve researchers' understanding of the relationship between strategic voting and ticket splitting. This is achieved by exploring new quantitative measures. The three selected countries do not use identical electoral systems, but their common characteristic is that they provide an opportunity for voters to split their ballot between an individual candidate running in a single-member constituency and a party list. This makes it possible to compare the two different types of votes and to search for patterns indicating strategic behavior. In this article, the authors introduce two analytic tools: one for determining the approximate quantity of split ballots and another for measuring strategic voting patterns based on the concentration of split tickets.
