Wednesday, October 28th, 2009What are the differences between z-distribution and t-distribution?
Tuesday, October 27th, 2009The Z distribution is just a special case of the normal distribution, with an idealized mean of 0 and standard deviation of 1. This allows us to create a compact and useful table for all normal distributions — a very important property before the days of fancy calculators and computers.
The t distribution is similar to the Z distribution, but is sensitive to sample size and is used for small samples, or moderate size samples when the population standard deviation is unknown. It is little different from Z for large sample sizes.
