First, note that the cumulative frequency of the first event, value, or class is the same as the frequency of the event, value, or class. All Rights Reserved. The SORT function then sorts this data in ascending numerical order. That means you can replace the above Frequency formula with a COUNTIF formula as below. The graph will then touch the \(X\)-axis on both sides. Oxford Cambridge Candle Jars, Daniel Smith is automation consultant with a passion for technology, data, AI, and machine learning.
