The sample size would have to be quadrupled . 樣本量必須增大三倍。
Sampling techniques and sample size requirements vary with the techniques used . 取樣方法和取樣多少的要求因所采用的測試方法而異。
If, however, the sample sizes are large enough, we do not need the assumption of normality . 如果樣本容量充分大,就不必做正態(tài)假設(shè)。
A sample size needs to be established when this method of mass flow measurement is used . 在使用這種質(zhì)量流量測量方法時,需要測定試樣的大小。
In general, the t distribution is flatter than the normal distribution, and there is a different t distribution for every possible sample size . 一般地說,t分布比正常分布更平坦一些,對于不同的樣本容易都有一個不同的相應t分布。
