Next topic, I learn about sampling method. In this topic, I will learn about population, sample and other statistical, types of variables, and the theory of sampling. In the topic about population, I learn more about the meaning of population, sample, variable, and random variable. I also learn about parameter, statistic, probability, and distribution. Other than that, I also know that there were 2 types of samples which is independent sample and dependent sample. Independent sample is when member of the sample is not related to others member while dependent means each member of one sample is paired with a member of the other sample. There also have types of variables which is qualitative and quantitative. Qualitative can be placed into distinct categories, according to some characteristic or attribute. For example, gender while quantitative is numerical and can be ordered or ranked for example age. Next, I also learn about types of sampling that had 2 types which is probability, and non-probability. Probability has four types. For example, simple random, stratified random, random systematic, and cluster random while probability have one which is convenience.
