what are the mean and the mode of the following set of data 5,12, 1, 5, 7

OpenStudy (kuoministers):

first step is to arrange in ascending order(smallest to largest)

OpenStudy (anonymous):

Ok

OpenStudy (kuoministers):

The mean is the where you add up all the numbers and then divide by the number of numbers. The mode is the value that occurs most often.

OpenStudy (anonymous):

Geesh

OpenStudy (kuoministers):

Best to have a habit to arrange from smallest to largest because normally they ask you to find the median

OpenStudy (anonymous):

But 5 is twice

OpenStudy (kuoministers):

if 5 is twice it occurs the most right? so 5 is the mode

OpenStudy (anonymous):

So the rest of the numbers are the mean?

OpenStudy (anonymous):

So I divide by five

OpenStudy (kuoministers):

you would need to add everything together 5 + 12 + 1+ 5 + 7. Then you count how many numbers there is then divide it

OpenStudy (kuoministers):

it would equal 30. So after you would divide 30 by 5 which the mean is 6

OpenStudy (anonymous):

Wow I got it thanks

OpenStudy (kuoministers):

OpenStudy (anonymous):
