We consider various data-analysis queries on two-dimensional points. We give new space/time tradeoffs over previous work on semigroup and group queries such as sum, average, variance, minimum and maximum. We also introduce new solutions to queries rarely considered in the literature such as two-dimensional quantiles, majorities, successor/predecessor and mode queries. We face static and dynamic scenarios.
