Politicians commonly believe that they must make their political statements (often called sound-bytes) very short because the attention span of listeners is so short. A similar effect occurs in reporting statistical news. Major statistical studies are often reduced to one or two sentences. A summary of a statistical report, taken from a news source, is given below. Describe what crucial information is missing in the given statement below and what more should be known, before the report is acted on. A newspaper reports on a poll claiming that the percentage of adults with a "great deal of confidence" in military leaders stands at 54%.Choose the correct answer below. A. The summary does not give enough information to determine whether the study was an observational study or an experiment. B. The summary gives all of the pertinent information for interpreting the study. C. No information is given about how the researchers defined "a great deal of confidence" or how they asked questions about it. The sample size and margin of error are not provided. D. The summary does not give a specific quantity for the amount of adults that have confidence in military leaders. It merely states that "a great deal" of adults have 54% confidence in military leaders, with no definition of "a great deal."

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
