What is a representative sample? What is its value?
Choose the correct answer below
A. A representative sample is a sample that is selected at random from the population of interest. It is valuable because its unbiased nature allows descriptive statistics to be applied.
B. A representative sample is a sample that exhibits characteristics typical of those possessed by the population of interest. It is valuable because these characteristics allow descriptive statistics to be applied.
C. A representative sample is a sample that is selected at random from the population of interest. It is valuable because its unbiased nature allows inferential statistics to be applied.
D. A representative sample is a sample that exhibits characteristics typical of those possessed by the population of interest. It is valuable because these, characteristics allow inferential statistics to be applied.
A representative sample is a group that closely matches the characteristics of its population as a whole. With inferential statistics, you are testing a hypothesis and drawing conclusions about a population, based on your representative sample.
Thus, the correct option is,
D. A representative sample is a sample that exhibits characteristics typical of those possessed by the population of interest. It is valuable because these characteristics allow inferential statistics to be applied.

Select all of the statements that are true for representative samples. Simple random sampling is used to collect the sample. The size of the sample is greater than 30 to ensure greater accuracy in the results of the study. Every member of the population has an equal probability of being selected to participate in the study. The relevant characteristics of the population are included accurately in the members of the sample. The intended results of the study are unbiased and can be generalized to the...
An article in a reputable journal discussed several data collection methods for testing the efficacy of a new program designed to reducedrug-related crimes in a city. The sample consisted of 56 "hot spots"long dash—areas of the city with a high crime rate but not necessarily a high drug crime rate. In Method 1, the new program will be implemented in half of the 56 hot spots (selected at random); the other half will not implement the program (the "no treatment"...
A sample is to be selected from a large population using simple random sampling. The proportion of subjects in the sample that have a given characteristic is to be calculated. Which of the following best describes the sample proportion? A. It is a lurking variable whose value is unknown. B. It is a statistic, which is unbiased for the population parameter only if the population is at least 100 times larger than the sample. C. It is a parameter. D....
1. When conducting a survey, it is important to use a random sample: to get a significant result. to avoid bias and to get a representative sample. so that we can make causal conclusions. to ensure truthful answers to the survey's questions. none of the above. 2. In order to obtain a sample of undergraduate students in the United States, a simple random sample of 10 states is selected. From each of the selected states, 10 colleges or universities are...
Help dentihy the sampling techniques used, and discuss potential sources of bias (f any). Explain. Assume the population of interest is the student body at a university Questioning students as they leave an athletic facility, a researcher asks 378 students about their dating habits What type of sampling is used? OA. Systematic sampling is used, because students are selected from a list, with a foxed interval between students on the list Cluster sampling is used, because students are divided into...
The faculty senate at a large university wanted to know what proportion of the employees thought the food services at the university are satisfactory. The statistics department offered to cooperate in conducting a survey, and a simple random sample of 100 faculty members was selected. A survey form was sent by email to these 100 employees. In this case, the population of interest is: all the employees who are faculty members. all the employees at the university. all the employees...
This Question: 2 pts Aquality control technician selected a simple random sample of 1500 tablets of a n al supplement being produced at a company's manufacturing facility. The average weight of the tablets from this sample was a miligrams The technician knows from past losting that the standard deviation of all tablets produced at the facility is miligrams. Assuming al tablet weight in the sample are independent of each other are the conditions satisfied to use the sample methods to...
