People substitute various combinations of cinnamon, nutmeg, allspice, coriander, and ginger, but you won't get something that tastes like cardamom. Not that it won't be good, it just won't be cardamom. Scout around for ethnic markets; it will often be cheaper there. Middle Eastern or Indian are what I'd try first.
The t-test and the one-way analysis of variance (ANOVA) are the two most common tests used for this purpose. The t-test is a statistical hypothesis test where the test statistic follows a Studentâs t distribution if the null hypothesis is supported. This test is applied when the test statistic follows a normal distribution and the value of a scaling term in the test statistic is known.
The Tukey HSD is therefore preferable to ANOVA in this situation. Some textbooks introduce the Tukey test only as a follow-up to an ANOVA. However, there is no logical or statistical reason why you should not use the Tukey test even if you do not compute an ANOVA. You might be wondering why you should learn about ANOVA when the Tukey test is better.
