10 Questions
Match the following terms with their definitions based on the text:
Simple random sample = A method where each member of the population has an equal and independent chance of being selected Population = The total members in a defined group Sample = A subset of the population used for study Bias = A systematic error in the sample selection that affects the results
Match the following statements with their corresponding implications:
The larger a random sample is in size = The more likely it is to represent the population Any differences that do occur are the result of chance = There's no bias in the selection process Everyone would have the same chance of being selected = The sampling procedure is random If the sample is large, this method is the best way = To obtain a sample representative of the population
Match the following terms with their descriptions:
Chance = The occurrence of events in the absence of any obvious intention or cause Representativeness = The degree to which a sample is similar to the population Random = Made, done, or happening without method or conscious decision Bias = Inclination or prejudice for or against one person or group
Match the following terms with their definitions:
Random sample = A subset of individuals randomly selected by researchers to represent an entire group Population = The entire group that researchers are interested in Sample = A part of the population that is subject to research Bias = An error that is introduced into the sampling process
Match the following terms with their explanations based on the text:
Sampling procedure = The method or process of selecting a portion of the population for study Chance = The reason for any differences that occur in a random sample Sample size = A factor that influences the likelihood of a sample representing the population Bias = Something that is not present in a simple random sample
What is a simple random sample?
A sample in which each member of the population has an equal chance of being selected
What is the likelihood of representativeness with large random samples compared to other methods?
Greater
What is the result of any differences between the sample and the population in a random sample?
The result of chance
In a random sample, what is the chance of being selected for each member of the population?
Equal
What is the best way yet devised to obtain a sample representative of the population of interest?
A large random sample
