If there are outliers, IQR is a better measure of the spread of data than range. The range will include the outliers, and make the data appear to have many more terms of a greater/lesser value than it has in reality. IQR shows the middle 50%, which (usually) doesn't contain outliers, so the majority of the data spread would be shown by IQR in a data sample with a significant amount of outliers. If your measure of the spread of data contains outliers, then the measure isn't accurate.

Answer:
Standard form = 606000
Scientific notation = 6.06*10^5
Step-by-step explanation:
Given the expression
(8.08×106)×(7.5×10−2)
This can also be expressed as;
(8.08*7.5) * (10^6*10^-2)
= 60.6*10^4
= 606000
express in scientific form;
606000
= 60.6*10^4
= 6.06*10^1*10^4
= 6.06 * 10^5
Answer:
A. 16.86 square inches
Step-by-step explanation:
Area of Circle = 
, where r = radius.
Area of Rectangle = 
, where l = length and w = width.
We are given the radius of the circle as 1, and we use π as 3.14
Next, we find the area of the rectangle.
Lastly, we subtract 3.14 from 20.
Therefore, the answer is A. 16.86 square inches.
