Step 1 We have given that the following set of data: 13, 8, 10, 7, 13, 9, 7, 11, 12, 10, 13. Multimodal: If the data set have one value repeated more than twice i.e. a value more than two times then that value is called multimodal. Step 2 Hence, The data set is said to be multimodal because 13 is three times in the data.
