Abstract: A system and method for analyzing large data sets to determine variances is described. In an example implementation, the system may include an observability platform configured to receive a user request to perform a variance analysis in association with a user-selected dataset on an observability platform. Data representing the user-selected dataset may be retrieved based on the request and may include many dimensions of data on the observability platform. Baseline and outlier representative samples may be generated based on the user-selected dataset. A server may be configured to include a variance analysis engine to perform the request for variance analysis. The observability platform may generate a plurality of data visualizations based on a result data set of the variance analysis. The data visualizations may be ranked using one or more disparity data metrics and may be provided for display in an order based on the ranking on the observability platform.
