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.
D) collective nouns describe more than one person, object, animal, or object.

Read this excerpt from a speech.
I have had my share of scrapes and cuts; I have even had stitches and a broken pinky finger. None of these injuries slowed me down much, and I never gave much consideration to the care I received. Maybe you are like me, charging through life, assuming other people will take care of the bumps and bruises you incur. Well, the community center has a first-aid class that might allow you to take charge of your own health. And who knows? A certification from this course might qualify you to apply for babysitting or lifeguarding jobs in the future.
