In a probability histogram, the height of each bar shows the true probability of each outcome if there were to be a very large number of trials (not the actual relative frequencies determined by actually conducting an experiment). In statistics, histograms are used to graph the probability distribution of the data. The smaller the interval we use for the histogram, the more we know about the data from the picture. Copy and paste the first column from the excel files to a variable named X. I created samples with a mean of 100 and standard deviation of 25, function RandNormalDist(100, 0.25).

The height of each bar is equal to the cumulative relative number of observations in the bin and all previous bins. Check Analysis Toolpak. n the following example you can create a bell curve of data generated by Excel using the Random Number Generation tool in the Analysis ToolPak. / Excel Histogram Charts and FREQUENCY Function. Note 'pdf' does not support datetime or duration data. For categorical histograms, this is the same as 'probability'. You can always change the configuration of the bins if you’re not happy with what Excel has come up with. The height of the last bar is less than or equal to 1. This represents the percentage rate chance of any particular data point falling within each range. This loads the data analysis toolpak. Probability plots is an old method (Hazen, 1914), that has been extensively used, especially through the use of printed probability paper. Earlier versions of Excel™ did not directly support generating and plotting histograms. The Analysis Tools should be available on the Excel Ribbon under Data > Analysis > Data Analysis.
