我要比对的两组数据一组样本量300多,一组3000多,这两组数据能在stata里面是有ttest做他们二者的均值差值T检验吗?
stata里面的help是这样描述的:
Description
ttest performs t tests on the equality of means. The test can be
performed for one sample against a hypothesized population mean.
Two-sample tests can be conducted for paired and unpaired data. The
assumption of equal variances can be optionally relaxed in the unpaired
two-sample case.
