Explanation:
This is one of the most confused about combinations as per my experience .I would firstly tell a bit of grammar part and then clarify with real day to day usage .
THE CONFUSION IF AT ALL COMES IS BECAUSE OF TWO DIFFERENT USAGES OF WORD “HAVE” . THEY LOOK AND SOUND LIKE SAME BUT PLEASE TREAT THEM DIFFERENTLY . So let's separate them like one of them is same like “ “AM,ARE,WILL,SHALL, “ the helping or auxiliary verbs ,and the second. “have “ is just like “ drive, eat, drink, watch” the main verb “ or I prefer to call “ Action”.

Answer:
I think, after this election especially, voting is actually beginning to matter for more people. I think our population is (hopefully) beginning to realize that they <em>can </em>have an affect on who their leader is. A reason a powerful person may not necessarily want the average citizen to know this is because they want to stay in power. If we don't know we can make a difference, we can't hurt their power. A horrible way of thinking, but unfortunately the way many power-craving people behave.
The correct answer is: "Median is not affected by extreme values".
The median is the value located in the middle position of the sample, at the same distance for the upper and lower values. For instance, in this dataset {1, 4, 5, 8, 10, 12, 13}, the median is 8, in the fourth possition from the left and from the right.
It is usually compared with the mean. The main difference is that the mean is affected by outliers but the median is not. In the example used above, if substituting the value 13 for 100, the median would still be 8, as it would continue being in the fourth position from both sides.
On the other hand, the mean in the original dataset is 7.57, while after the modification it increases to 20.
