WebAug 19, 2024 · As mentioned earlier, we need a simple random sample and a normal distribution. If the sample is large, a normal distribution is not necessary. There is one more assumption for a pooled approach. That is, the variance of the two populations is the same or almost the same. If the variance is not the same, the unpooled approach is more … WebSuppose I have only two data describing a normal distribution: the mean $\mu$ and variance $\sigma^2$. I want to use a computer to randomly sample from this distribution such that I respect these two statistics. It's pretty obvious that I can handle the mean by simply normalizing around 0: just add $\mu$ to each sample before outputting the sample.
