When the assumption of a normal curve is seriously violated, the ordinary t test may give incorrect results. This is because the t test relies on the assumption of normality for the sampling distribution of the means, and if this assumption is not met, the t distribution may not accurately reflect the true distribution of the sample means. Therefore, it is important to use alternative non-parametric tests or to transform the data if the normality assumption is seriously violated.
