Why Are Statistics Important in Everyday Life?

Statistics help people make informed decisions all the time. For example, statistical evidence of the dangers of smoking causes people to quit, saving lives. Statistics are important in many fields that impact modern daily life, such as product safety within manufacturing and reliability engineering for electronics.

Quality assurance processes heavily rely on statistics. It is often impossible to fully test all items that roll off a production line, so quality assurance staff check a statistically significant sample of products to ensure safety and quality standards are met. Without this process, there is less assurance that common goods or appliances, such as laptop chargers, are safe to use. More generally, statistical analysis enables reliability engineers to ensure the functionality of systems that people depend on every day, especially within the telecommunications and electronics industries.
