Frequency Histogram - an overview | ScienceDirect Topics
2.1 Frequency Histograms. To draw a histogram, the range of data is subdivided in a number of equally spaced bins. Thus, frequency histograms report on the horizontal axis the values of the measured variable and on the vertical axis the frequencies, that is, the number of measurements, which fall into each bin. The number of bins influences the ...
