T Distribution (Definition and Formula) Student
WebIf we plot Student T distribution, it would look very much like a bell-shaped curve. Therefore the student-t distribution resembles a normal distribution. Furthermore, the properties of t-distribution are closer to the normal distribution. As an instance, the mean of the distribution is 0. The most important point to note is that the student-t ... Webju lee. when n (sample size) is greater or equal to 30, can we use use z statistics because the sampling distribution of the sample mean is approximately normal, right? if this is the case, then why does t table contain rows where the degree of freedom is 100, 1000 etc (i.e. degree of freedom = n - 1)? if n is greater or equal to 30, we would ...
