| 1. | If, however, the sample sizes are large enough, we do not need the assumption of normality . 如果样本容量充分大,就不必做正态假设。 |
| 2. | If we wish to avoid the inaccuracies caused by the size of the sample, we need to use the t distribution . 为了避免因样本容量大小而造成的误差,我们必须使用T分布。 |
| 3. | An inclusion of 350 patients in total , with a follow - up of 3 years is foreseen 试验样本容量为350人,试验时限为3年。 |
| 4. | Investigates the survey manner , sampling method and calculation of sample size 就调查方式、抽样方法和样本容量的计算进行了探讨。 |
| 5. | Will estimators become approximately normally distributed when sample size gets large 当样本容量变大时是否估计量会渐近地趋向于正态分布? |
| 6. | If we wish to avoid the inaccuracies caused by the size of the sample , we need to use the t distribution 为了避免因样本容量大小而造成的误差,我们必须使用t分布。 |
| 7. | Commonly , subgroup size , sampling rate , and control limit are three main parameters in designing a control schemes 通常样本容量、抽样比例和控制线的选择是设计控制图的三个主要指标。 |
| 8. | The graduated 200 < mu > l tips have a reference mark at 10 < mu > l so you can check pipettor calibration and visually estimate sample size 200微升刻度的吸头,在10微升处有基准标记,可检查移液器刻度和估计样本容量。 |
| 9. | Unbiased estimators are not necessarily consistent , but those whose variances shrink to zero as the sample size grows are consistent 无偏估计量未必是一致的,但是那些当样本容量增大时方差会收缩到零的无偏估计量是一致的。 |
| 10. | The research measures improvement features with five aspects - data collection , sample source , sampling measure , sample capacity and feet back rate 国际商业研究方法的完善性主要体现在数据收集方法、样本来源、抽样方法、样本容量和反馈率5个主要方面。 |
