1. The problem is to find the mode of a given data set. 2. The mode is the value that appears most frequently in a data set. 3. To find the mode, list all the values and count how many times each value occurs. 4. The value with the highest frequency is the mode. 5. If no value repeats, the data set has no mode. 6. If multiple values have the same highest frequency, the data set is multimodal and all those values are modes.
