Quizplus · Accepted Answer

The t statistic is calculated using the sample size and sample standard deviation, and is used when the population standard deviation is unknown. It is appropriate for small sample sizes when the data follows a normal distribution. For large sample sizes (usually considered to be over 30), the t distribution becomes very similar to the standard normal distribution, which allows for the use of z-scores instead of t-scores. Therefore, the statement that the t statistic is calculated by assuming that the sample size is large is false.
