Stratified sampling Cluster sampling Systematic sampling Multistage sampling Quota sampling Disproportionate stratified sampling Post-stratification # Stratified sampling: In stratified sampling, the population is divided into distinct subgroups or strata based on one or more characteristics (e.g., age, gender, income level). A random sample is then selected from each stratum, ensuring proper representation of all strata in the overall sample. This method is useful when the population is heterogeneous and there are potential variations in responses between different subgroups. # Cluster sampling: In this method, the population is divided into clusters or groups (e.g., geographic regions, schools, households), and a random sample of clusters is selected. All members within the selected clusters are then included in the sample. This method is often used when it is impractical or expensive to create a comprehensive list of all individuals in the population. # Systematic sampling: This...

Stratified sampling is a technique used in survey research and statistical analysis when a population contains different categories or strata with potential variations in responses between these categories. This method ensures that each stratum or category gets proper representation in the sample by creating distinct subgroups or strata within the population and then selecting a sample from each stratum. The key steps in stratified sampling are: 1. Identify the relevant strata or categories within the population based on specific characteristics or variables of interest, such as age, gender, income level, geographic location, or any other relevant factor. 2. Determine the desired sample size for each stratum, which can be proportional to the stratum's size within the population (proportionate stratified sampling) or based on other considerations (disproportionate stratified sampling). 3. Randomly select individuals from each stratum using simple random sampling or other appropriate...

1. Performance:    - The H100 delivers up to 30 times higher performance compared to the previous-generation A100 GPU.    - It can achieve up to 236 teraflops of AI performance, making it the world's most powerful accelerator.    - This immense performance is enabled by its advanced Transformer Engine, which is optimized for large language models and other AI workloads. 2.
