The frequency of 1234 is going to be 2 for each of those numbers but the graph shows different result it shows 4 for the bin between 1 and 2. My code is as following ggplot MDmedianall aes x MD_median ydensity fill IDHtype geom_histogram alpha 05binwidth 000010 position identity geom_density. Although any basic software can construct a histogram it is important to know what your computer is doing behind the scenes when it produces a histogram.
Ill graph the same datasets in the histograms above but using normal probability plots. In this example the ranges should be. This video shows how to draw histograms. Import pandas as pd Generate data on commute times. See full answer below. Note that this is not a true histogram it is actually a bar chart.

The vertical axis of a bar chart is frequency but for a histogram should be density. Enter the relevant input range and bin range. The frequency of 1234 is going to be 2 for each of those numbers but the graph shows different result it shows 4 for the bin between 1 and 2. In this case 0 1 2 3 and 4. All you need to do is visually assess whether the data points follow the straight line. If the points track the straight line your data follow the normal distribution.
