To answer this, we need to order the values. In this case, those values are ordered from the least to the greatest, which means we do not need to do so.
The mean is the sum of all of the values divided by the number of values:
The mode is the value that repeats the most in this list of values. In this case, we have that this value is 108. So the mode is 108.
The median is the value for 50% of the values are below it and the other 50% of the values are above this value. In this case, we have 10 values. This is the case for an even number of values. We need to take the two central values and divide them by 2. These two values are 124 and 131. Then:
We have:
108,108,117,123,124,131,144,162,187,198
There are four values before 124 and four values after 131.
The range is the difference between the lowest value and the greatest value:
Then the range is 90.
Therefore, we have:
The mean is 140.2
The mode is 108.
The median is 127.5
The range is 90.
