On a normal distribution of iq test scores, the average score would be:
spayn [35]

The average IQ test score would be 100.

What is a normal distribution?

A probability distribution that is symmetric about the mean or average is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the average value occur more frequently than data that are far from the mean. The normal distribution appears as a "bell curve" on a graph.

Average IQ Score

A score of 100 is regarded as the average IQ on various tests. The majority of results (68%) are within one standard deviation of the mean (that is, between 85 and 115). This indicates that the average result is within plus or minus 15 points for almost 70% of test takers.

What is the perimeter of a rectangle where the width is "n+0.6" and the length is "n"
Damm [24]
2n + 2(n+0.6) = p
perimeter is all 4 sides added together in length.  Since we understand one of the sides as n, we can multiply by 2 to represent both of those sides.  We then understand the other side as n+0.6.  We can multiply that by 2 to represent the other two sides.
Adding the representation of 2 sides to the representation of 2 sides will equal the perimeter if we ever discover what n is numerically.
