A Z-table is a statistical table used to find probabilities of a normal distribution. It is a table of critical values that correspond to a standard normal distribution with a mean of 0 and a standard deviation of 1. The Z-table is also known as a standard normal distribution table or a Gaussian distribution table.

The Z-table is typically used to find the probability that a random variable lies within a certain range of values. It is commonly used in statistical analysis, data analysis, and quality control. The Z-table is a vital tool for researchers, statisticians, and analysts to analyze and interpret data.

  • Standardize the data: Convert the data into a standard normal distribution by finding the Z-score.
  • Find the Z-score: Use a Z-table or a calculator to find the corresponding Z-score.
  • Find the probability: Use the Z-score to find the probability that the data point lies within a certain range of values.

For example, let's say you want to find the probability that a stock price will increase by 10% within a certain time frame. You would standardize the data by finding the Z-score, then use a Z-table to find the corresponding probability.
