A truly random sample needs to have randomization. Randomization is the key point to a random sample. To get a random sample one needs to identify their target population, get a representative sample of that target population-which can be obtained from a sampling frame.

Sampling Distributions Review. 1. The Wechsler Adult Intelligence Scale (WAIS) is a common “IQ test” for adults. The distribution of WAIS scores for persons over 16 years of age is approximately normal with mean 100 and standard deviation 15. A. What is the probability that a randomly chosen individual has a WAIS score of 105 or higher?

Quantitative Sampling Methods. Simple Random Sample (SRS) A simple random sample occurs when every unit in the population is known is accessible, and has an equal probability of being selected. Indeed, SRS is the simplest and least complicated sampling technique to administer. Conversely, it is the most difficult to achieve.
