First arrange the numbers from smallest to largest:
12 , 13, 14, 14, 14
Mean is the average. Add the numbers together and divide by the quantity of numbers:
12 + 13 + 14 +14 +14 = 67
67/5 = 13.4
Mean = 13.4
Median, is the middle value, since there are 5 numbers, the mode would be the 3rd value, which is 14.
Mode is the value that appears the most. There are 3 number 14's, so the mode is 14.
Answer:
Mean = 13.4
Median = 14
Mode = 14
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 5 values, so N = 5.
These values are 14,14,12,13,14. So S = 14+14+12+13+14 = 67
Mean = 67/5 = 13.4
-------------------------------------------------------------------------------
For the median, the first step is to sort all the elements in a crescent way.
So 12 13 14 14 14
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, 14 appears 3 times, 12 and 13 appear once each. So the mode is 14
