The standard normal distribution is a statistical concept with a mean of 0 and a standard deviation of 1. It's used for probability calculations and data analysis, allowing for the comparison of different data sets through z-scores. This distribution is crucial for benchmarking performance and determining unknown parameters in normal distributions. Understanding and utilizing standard normal distribution tables is key for statistical analysis.
