1. SAMPLING METHODS AND DESCRIPTIVE STATISTICS FOR SAMPLES

2. SAMPLING METHODS AND DESCRIPTIVE STATISTICS FOR SAMPLES ENGR. AAB YALONG The main purpose of sampling in research is to make the research process doable. The research sample helps to reduce bias, accurately presents the population, and is cost-effective. Studies that use samples are less expensive, and the study of the entire population is sometimes impossible. Thus, the goal of sampling is to ensure that the sample group is a true representative of the population without errors. The term error includes sampling and non-sampling errors.

3. SAMPLING METHODS AND DESCRIPTIVE STATISTICS FOR SAMPLES ENGR. AAB YALONG Population vs. sample First, you need to understand the difference between  a population and a sample , and identify the target population of your research. The  population  is the entire group that you want to draw conclusions about. The  sample  is the specific group of individuals that you will collect data from.

4. SAMPLING METHODS AND DESCRIPTIVE STATISTICS FOR SAMPLES ENGR. AAB YALONG To draw valid conclusions from your results, you have to carefully decide how you will select a sample that is representative of the group as a whole. This is called a  sampling method . There are two primary types of sampling methods that you can use in your research: Probability sampling  involves random selection, allowing you to make strong statistical inferences about the whole group. Non-probability sampling  involves non-random selection based on convenience or other criteria, allowing you to easily collect data.
