Random number tables have been used in statistics for tasks such as selected random samples. This was much more effective than manually selecting the random samples (with dice‚ cards‚ etc.). Nowadays‚ tables of random numbers have been replaced by computational random number generators. Tables of random numbers have the desired properties no matter how chosen from the table: by row‚ column‚ diagonal or irregularly. The first such table was published by a student of Karl Pearson’s in 1927‚ and

11 (i) SAMPLE DESIGN AND SAMPLING PROCESS Introduction Samples are parts or potions of population. A population is the specified total of study elements. A target population‚ also known as the universe‚ includes all the members of a real or hypothetical set of people‚ event or objects to which we wish to generalize the results of our research. A study population is that aggregation of elements from which the sample is actually selected. Sampling means selecting a given number
Free Sampling
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
