What percent of the population has an intelligence quotient below 100?A. 75% B. 50% C. 35% D. 10%

1. Understand IQ Distribution: 

IQ scores are typically distributed in a bell curve (normal distribution) with a mean of 100.
2. Median IQ Score: 

The median (middle value) of a normal distribution is the same as the mean.
3. Percentage Below Mean: 

In a normal distribution, 50% of the population falls below the mean.
 

Supplemental Knowledge:

Intelligence Quotient (IQ) scores are typically distributed in a bell curve, also known as a normal distribution. The average IQ score is set at 100, with the majority of the population falling within a certain range around this average.

Key Points about IQ Distribution:

1. Normal Distribution:
- In a normal distribution, the mean (average) is 100.
- The distribution is symmetrical, meaning that 50% of the population has an IQ below the mean and 50% has an IQ above the mean.

2. Standard Deviation:
- The standard deviation for IQ scores is usually set at 15 points.
- This means that approximately 68% of people have an IQ between 85 and 115 (within one standard deviation of the mean).

Life in Context:

Knowing how IQ scores are distributed is extremely useful for various contexts: for instance, educational systems rely on this knowledge to identify students who might require extra support or those eligible for advanced programs.

Imagine you work in educational psychology and need to assess whether a student might require special education services. Knowing that half of all children tend to fall below an IQ score of 100 helps you interpret test results accurately.
