Which shows the mean, median, mode, and range for this set of data? 8.3, 4.5, 6.2, 9.6, 4.3, 11.2, 5.9, 9.7, 10.5

8.3,4.5,6.2,9.6,4.3,11.2,5.9,9.7,10.5

Mean: 
To find mean you do the same as you would to find an average. Add up all of the numbers and divide by how many numbers are there. So, 
8.3 + 4.5 + 6.2 + 9.6 + 4.3 + 11.2 + 5.9 + 9.7 + 10.5 = 70.2 
Then divide by 9 since you have 9 numbers.
70.2 / 9 = 7.8 

Median:
To find median you set up the data from least to greatest and cross out one number from each side until you are left with one number as the middle number.
4.3, 4.5, 5.9, 6.2, 8.3, 9.6, 9.7, 10.5, 11.2 
       4.5, 5.9, 6.2, 8.3, 9.6, 9.7, 10.5
              5.9, 6.2, 8.3, 9.6, 9.7
                     6.2, 8.3, 9.6
                         = 8.3 
Mode:
Mode is the most, meaning the number that appears the most in your set of data. In this case there is no mode because in your set there is no number that occurs more than once.

Hope this helps!

The answer would be (c)
