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.
ANOVA â Analysis of Variance ! Analysis of variance is used to test for differences among more than two populations. It can be viewed as an extension of the t-test we used for testing two population means. ! The specific analysis of variance test that we will study is often referred to as the oneway ANOVA. ANOVA is an acronym for ANalysis Of VAriance. The adjective oneway means that there is a single variable that defines group membership (called a factor). Comparisons of means using more than one variable is possible with other kinds of ANOVA analysis. 2
