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.

## Key Concepts

### Standard Normal Distribution

The standard normal distribution is a fundamental tool for probability calculations and data analysis, representing a normal distribution with a mean of 0 and a standard deviation of 1

### Probability Density Function

The probability density function for the standard normal distribution is used to depict the probability of z-values within the distribution

### Z-Scores

Z-scores, or standard scores, are numerical measurements that describe a value's relationship to the mean of a standard normal distribution

## Applications

### Standardization Process

The standardization process involves converting a normally distributed variable into a standard normal variable using the transformation formula

### Probability Calculations

The standard normal distribution is used to calculate the likelihood of a variable falling within a specific interval

### Performance Comparison

The standard normal distribution allows for the comparison of performances across different data sets with varying means and standard deviations

## Problem Solving

### Unknown Parameters

The standard normal distribution can be used to solve for unknown parameters such as the mean or standard deviation in normal distributions

### Simultaneous Equations

Simultaneous equations can be established using z-scores to solve for unknown parameters in normal distributions

## Tools

### Standard Normal Distribution Tables

Standard normal distribution tables are essential tools for calculating probabilities and can be found in statistical textbooks and resources
