Depending on how a sample is drawn‚ it may be a random sample or a nonrandom sample. A random sample is a sample drawn in such a way that each member of the population has some chance of being selected in the sample. In a nonrandom sample‚ some members of the population may not have any chance of being selected in the sample. Suppose we have a list of 100 students and we want to select 10 of them. If we write the names of all 100 students on pieces of paper‚ put them in a hat‚ mix them‚ and then

Unlike a computer memory‚ humans have a cognitive memory system that selectively takes information from the senses and converts it into meaningful patterns that we store and access later as needed. These memory patterns‚ then‚ form the raw material for thought and behavior‚ which in turn enables you to recognize a friend’s face‚ ride a bicycle‚ recollect a trip six flags‚ and

There are many ways to select a random sample. Four of them are discussed below: Simple Random Sampling: In this sampling technique‚ each sample of the same size has the same probability of being selected. Such a sample is called a simple random sample. One way to select a simple random sample is by a lottery or drawing. For example‚ if we need to select 5 students from a class of 50‚ we write each of the 50 names on a separate piece of paper. Then‚ we place all 50 names in a hat and mix them thoroughly
