What is a representative sample? What is its value?
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...

Statistics Discussion Questions We're going to start doing some more traditional inferential statistics that will allow us to determine whether there are differences between (a) a sample and a population, (b) multiple different samples. The former will require us to use one-sample t-tests (Chapter 13), and the latter will require us to do independent and dependent samples t-tests and ANOVAs. Forgetting about the actual procedures, give me an example of real-world research questions that would require you to do each...

a. Distinguish between description and inference as reasons for using statistics. b. Suppose you have data for a population, such as obtained in a census. Explain why descriptive statistics are helpful, but inferential statistics are not needed. a. Which statement below best distinguishes description from inference? A. Statistical inference provides useful summaries of the data, while description helps make predictions and decide whether observed patterns are meaningful. B. Statistical inference provides useful summaries of data for a sample, while description...

In each of the following statements, determine whether the branch of statistics is best classified as descriptive statistics or inferential statistics. A. The average of a data set is equal to 35.7. B. The minimum value of a data set is 78, and the maximum value is 146. C. Since the average age in a sample is 23, it is likely that the average age in the population is about 23. D. Since the values in the sample are so...

Distinguishing Between Inferences and Assumptions To be skilled in critical thinking is to be able to take one’s thinking apart systematically, to analyze each part, assess it for quality and then improve it. The first step in this process is understanding the parts of thinking, or elements of reasoning. These elements are: purpose, question, information, inference, assumption, point of view, concepts, and implications. They are present in the mind whenever we reason. To take command of our thinking, we need...
