You need to remember the formula of mean of numerical elements such that:
Mean = sum of elements/the number of elements
Mean = `(15 +20 + 25 + 30 + 35 + 40 + 45 + 50 + 55)/9`
Mean = 35
Notice that the mean is the middle numerical element 35.
You need to remember that the median is the middle term, hence, because you don't need to put the numbers is order, you may tell that the median = 35. Notice that mean = median = 35.
Notice that there is no mode since each number appears just once.
Hence, the mean is equal to median = 35 and there is no mode for the list of numbers 15, 20, 25, 30, 35, 40, 45, 50, 55.

To find the mean: add the numbers up together and then divide by the total number of scores.
mean = 35
the median is the middle number
15, 20, 25, 30, 35, 40, 45, 50, 55
median= 35
Mode is the number that repeats the most, so there are no mode as there are no numbers that repeat
Mean:35
Median:35
Mode:no mode
to find the mean you add up all the numbers which equals 315 then you divide that by 9 and that equals 35 so the mean is 35. to find the median you put the numbers in order and cross out the smallest then largest so on and take the middle number if you have 2 numbers you add them up and divide by 2 so the median is 35. to find the mode all that is the number that appears the most which they all appear once so there is no mode there can be more then 1 mode.
