What are the mean and the mode of the following set of data: 5, 12, 1, 5,
The mean is the average of all the numbers. So, 5+12+1+5=23. Then divide by how many numbers there are. So in this case there are 4, so take 23/4. Which equals 5.75. Next the mode is the number that occurs the most l, so it would be 5.
you have to add the numbers their are and divideby how many numbers there are and the mean is 5.75
