Detailed Solution

As we know,
●       The median is the middle observation of the data set.
●       The term in the data that occurs a maximum number of times is known as mode.
●       The arithmetic mean of data is the sum of all observations divided by the total number of observations.
From the above definitions of mean, mode, and median we understand that there is no need to arrange data for finding the mean but for median and mode it is required to arrange the data either in ascending or descending order.
Hence, option 3 is correct.
