A central challenge of biology is to understand how individual cells process information and respond to perturbations. Much of our current knowledge is based on ensemble measurements. However, cell-to-cell differences are always present to some degree in any population of cells, and the ensemble behaviors of a population may not represent the behaviors of any individual cell. Here, we discuss examples of when heterogeneity cannot be ignored, and describe practical strategies for analyzing and interpreting cellular heterogeneity; while ensemble measurements may be too simplistic, capturing all variation among cells may be unnecessary. To develop accurate models of individual cell behavior–be they in the form of cartoons, words, or mathematics–it is essential to identify which cell-cell differences are important and which can be ignored.
