Answer:
Mean = 15.5
Median = 14
Mode = 12
Range = 12
Step-by-step explanation:
The mean is the sum of all the values divided by the number of values.
So mean = S/N.
There are 9 values, so N = 9.
These values are 18,12,14,12,16, 24,18,12,14. So S = 18+12+14+12+16+24+18+12+14 = 140
Mean = 140/9 = 15.5
-------------------------------------------------------------------------------
For the median, the first step is to sort all the elements in a crescent way.
So 12 12 12 14 14 16 18 18 24
Then you will need to consider whether N is even or odd.
If N is even, to find the median you need to sum the values at the positions N/2 and (N/2)+1 and divide by 2.
In this case, N is odd. So the median will be the value at the position (N+1)/2, which is 14.
--------------------------------------------------------
The mode is the value that appears most often in a set. In this set, 12 appears 3 times, 14 and 18 appears twice and while 12 and 13 appear once each. So the mode is 12.
--------------------------------
The range of a set is:
Highest value - Smallest Value
In this set: range = 24-12 = 12
