Determining the range for histogram bins depends on the data's context and the message intended to be conveyed. Options for binning include fixed intervals, like every ten or twenty years, or specific age ranges that reflect demographic categories. The width of bins does not have to be uniform; it can vary based on the data's distribution and the desired clarity of the histogram. When calculating bins from a given data set, the range can be determined by dividing the difference between the maximum and minimum values by the number of bins. Proper bin selection is crucial for accurately representing the data.
