Given the box plot, will the mean or the median provide a better description of the center? a. The Mean, because the data distribution is symmetrical

b. the median, because the data distribution is symmetrical.

c. the mean, because the data distribution is skewed to the right.

d. the median, because the data distribution is skewed to the right

Answers

From the given box plot we can see that there are more values towards the right end than are on the left end.

This means the data is skewed towards right. A symmetrical box plot has same number of values on both sides of the median.

Whenever we are dealing with skewed graphs, the best option to choose from mean and median is always the median. This is because due to large number of data values on the one side, the mean will always be closer to that side. Median is not largely affected in this case.

Therefore, the correct answer would be option D.
The median, because the data distribution is skewed to the right
D. Mean always goes toward the skewness due to outliers.
Median is minimally affected by outliers.

Jayne stopped to get gas before going on a road trip. The tank already had 4 gallons of gas in it. Which of the statements below best describes why the graph relating the total amount of gasoline in the tank, y, to the number of gallons that she added to it, x, will be continuous or discrete? A. The graph will be continuous because the amount of gas that she added to the tank does not need to be an integer amount. B. The graph will be continuous because we are not told a maximum value for the amount of gas. C. The graph will be discrete because there are already exactly 4 gallons of gas in the tank.

Answers

A. The graph will be continuous because the amount of gas that she added to the tank does not need to be an integer amount.
"The graph will be continuous because the amount of gas that she added to the tank does not need to be an integer amount" is the statement that best describes why the graph relating the total amount of gasoline in the tank, y, to the number of gallons that she added to it, x, will be continuous or discrete. The correct option is option "A".
