Question

Question 4 (1 point) Refer to the article. The box-plot: An exploratory analysis graph for biomedical publications: Suppose you have a data set, and you create both a boxplot and a graph of mean ± sd. You then add one value to the data set that is much smaller than any of the other points in the set and make both types of graphs again. What will happen? The boxplot will stay about the same, but add one outlier below the box; the mean ± sd will have a larger mean and smaller sd. A) 05) The boxplot will stay about the same, but add one outlier below the box; the mean t sd will have a smaller mean and larger sd. The boxplot will show a wider box and a longer lower tail, and add one outlier below the box; the mean t sd will have a smaller mean and targer sd. The boxptlot will how a wider box and a longer lower tail and Sela one outir below the box: the mean sd will stay about the same. er lower tail, and one outlier below the box; the mean ± sd wil D) The boxplot witt stay about the same, but add one outlier below the box; the mean ± sd will also stay about the same E) Save Question 5 (1 point)

Explanation / Answer

If we add one outlier at the lower end, boxplot will be having a larger lower tail and at the same time, mean will decrease and standard deviation will increase.

Hence,

Option C is correct.
