Quizplus · Accepted Answer

When comparing means with one small sample (i.e. sample size < 30), the appropriate statistical test is the t-test. The t-test is used to determine if the mean of the sample is significantly different from a hypothesized population mean. The Z-test is used when the sample size is large (i.e. sample size > 30), while the chi-square test and ANOVA are used for categorical and multiple groups comparisons, respectively.
