Answer:
A) Mean
Step-by-step explanation:
The mean of a data set is one of the ways to calculate the center of tendency, center of data, or the "average".
Example of a set of data: 4, 2, 1, 6
Mean = sum of data / number of data
= (4 + 2 + 1 + 6) / 4
= 13 / 4
= 3.25
Other incorrect answers:
Range - this shows the difference between highest and lowest values in a data set.
Using our example:
highest = 6; lowest = 1
Range = highest - lowest
= 6 - 1
= 5
Median - this shows the "middle" of data if you lined them up from least to greatest, and found the number in the middle.
Using our example:
4, 2, 1, 6
1, 2, 4, 6 Reorder from least to greatest
1, 2, 4, 6 Focus on the middle
(2 + 4)/2 = 3 Find the mean of the two middle numbers
Median = 3
Outlier - this names a piece of data that is far off from what the rest of the numbers are
In our example, we have no outliers.
However, if the data was 4, 2, 1, 6, <em>20</em>
Then the outlier would be 20.
