Student's t-test, in statistics, a method of testing hypotheses about the mean of a small sample drawn from a normally distributed population when the population standard deviation is unknown.
For a normally distributed population the quality of a given population sample can be assessed by comparing the sample frequency distribution to the normal distribution function.
Based on the plots and the normality tests, assume that the data are from a normally distributed population.
That is more than four times the rate found in what the researchers called "a normally nourished population".
Normally, Bremerhaven (population 113,000) can be ignored, as can Bremen, a larger town 54km away.
Writer and critic Cynthia Ozick claimed the novel "is the product, conscious or not, of a desire to divert [attention] from the culpability of a normally educated population in a nation famed for Kultur".
Each sample is drawn from a normally distributed population and/or the sample sizes are equal.
So it may be concluded that the data is derived from a normally distributed population.
Again we note that all these data did not come from a normally distribution population.
Therefore, the data from the experiments come from a normally distributed population, and they were reliable.
An OLS procedure was preferred due to the fact that the dependent variable was drawn from a normally distributed population.
