The standard normal distribution is used primarily because it simplifies statistical analysis and calculations. It has a mean of 0 and a standard deviation of 1, allowing for easy interpretation of z-scores, which indicate how many standard deviations a data point is from the mean. This standardization enables comparisons across different datasets and facilitates the use of various statistical techniques, including hypothesis testing and confidence intervals. Additionally, many inferential statistics rely on the properties of the standard normal distribution, making it a foundational tool in statistics.

What requirements are necessary for a normal probability distribution to be a standard normal probability?

For a normal probability distribution to be considered a standard normal probability distribution, it must have a mean of 0 and a standard deviation of 1. This standardization allows for the use of z-scores, which represent the number of standard deviations a data point is from the mean. Any normal distribution can be transformed into a standard normal distribution through the process of standardization.


What is the standard deviation of a standard normal distribution?

The standard deviation in a standard normal distribution is 1.


In the standard normal distribution the standard deviation is always what?

The standard deviation in a standard normal distribution is 1.


How does the standard normal distribution differ from the t-distribution?

The normal distribution and the t-distribution are both symmetric bell-shaped continuous probability distribution functions. The t-distribution has heavier tails: the probability of observations further from the mean is greater than for the normal distribution. There are other differences in terms of when it is appropriate to use them. Finally, the standard normal distribution is a special case of a normal distribution such that the mean is 0 and the standard deviation is 1.


In your own words describe the standard normal distribution?
