The emphasis is on understanding why one gets this type of behaviour, although some numerical tables are presented to illustrate the conclusions.NoelTheCressieTheWileyAustralian Journal of StatisticsCressie, NAC ( 1980 ) Relaxing assumptions in the one sample t-test . Austr. J. Stat. 22 : 143 ...
It's not practical to test them all, so your next objective is to work out which of these assumptions you should focus on testing.One way to do this task is to plot each assumption on an assumptions matrix. The vertical axis of the matrix shows the importance of the assumption. The ...
For example: "Do you think it would be helpful to have a dashboard that allowed you to see all your banking information in one place?" Pitch your product. For example: "I'm building a great, easy-to-use dashboard product that makes your life simpler and will be available for a small...

1. Independence: One of the fundamental assumptions of parametric tests is that the observations within a sample or between samples must be independent of each other. This means that the value of one observation should not be influenced by the value of another observation. Violating this assumption...
One of the many marvels of their landmark studies is that they rarely test their auxiliary assumptions. Rather, readers were trusted to agree about how people interpret the tasks (e.g., select anchors in studies of that heuristic). Subsequent studies have often accepted those interpretations in...

Though the T-Test is a valuable tool in statistics, numerous assumptions must be made before conducting one in order for it to be interpreted properly and with validity.
