Identify the measure of central tendency (mean, median or mode) that would be best for the following set of data.
0, 89, 92, 97, 99, 100

The correct answer is: Median, because there is an outlier. The outlier could be incorrect and would influence the mean too much.

Step 1 of 1:
Observe that, for the given data points, 0, 89, 92, 97, 99, 100; 0 is far away from the others.
So, 0 is an outlier in this case.
If there is the presence of an outlier then it will affect the mean of the dataset and we will not get a good measure of the center of the dataset. So, we opt out of the mean.
Hence, the median is a better choice.
Final Answer:
The right choice is-- a. Median, because there is an outlier. The outlier could be incorrect and would influence the mean too much.
