(I saw that when searching about mode in google). Our teacher tells a formula to find out mode, that is Z=L1+(F1-F0)/(2F1-F0-F2)*iį2 = just after the modal class frequency.į0 = just previous the modal class frequency.īut I saw in most of cases the highest frequency is the mode. Here is the 2008 question, from Saptarshi: Different Formulas for Calculating Mode That answer wasn’t archived, but when we got another question about it a year later, it was time to publish what I had figured out. I had never heard of such a formula until 2007, when a question was asked about applying it in a special case. We’ve had a number of questions about that formula. But some sources teach a formula for finding (actually just estimating) the mode. When data is grouped (binned) as in a histogram, we normally talk only about the modal class (the class, or group, with the greatest frequency), because we don’t know the individual values. The mode of a list of data values is simply the most common value (or values … if any).
