Go Deeper: What is a Frequency Histogram?
Like a histogram, frequency histograms show the spread or dispersion of data. Rather than sort the values into bins, a frequency histogram has one bin or bar per value.
In the frequency histogram above, there were no data points with a value of .0629 so there is no bar for that value. More importantly, many measurements fall outside of the LSL and USL which means that the process does NOT consistently deliver the customer's requirements.
Why Use a Frequency Histogram?
Use a frequency histogram whenever the data has a limited number of specific values (e.g., 0.65, 0.60, 0.55). This will show exactly how many of each value are in the sample. You can also draw a dot plot on this kind of data.
NOTE: If you have subgroups of data, make sure that your data set is plotted in ROWS of subgroups - NOT columns of subgroups. Otherwise your Cp/Cpk will be incorrectly calculated:
