SOLVED

41) In the following data set, what is the mean? ( 12, 0, 0, 1, 1, 1, 6, 10, 11 ) A) 4.66 B) 1 C) 42 D) 6 E) 1 and 0 42) Measures of variability are concerned with: A) central tendency. B) the degree to which respondents are “typical.” C) depicting “typical” frequencies among the values in a set. D) depicting the similarities between one data set and another. E) the degree to which respondents are “atypical.” 43) Which is the best description of a frequency distribution? A) the number of times a respondent answers each survey question B) depiction of the accumulative variance in a dataset C) the number of frequencies that normal distributions appear in a dataset D) the summary of the number of times each and every category appears for the entire sample E) depiction of the analysis that shows the value that occurs most often 44) For purposes of comparison, we can convert the frequency distribution by dividing the frequency of each value by the total number of observations, which results in a: A) comparative distribution B) variable distribution C) count distribution D) percentage distribution E) standard distribution 45) The ________ identifies the distance between the lowest value (minimum) and the highest value (maximum) in an ordered set of values. A) deviation B) mode C) frequency D) distribution E) range 46) One of the advantages of the standard deviation is that it is a measure of variation that is also: A) Measure of variability that uses a normal or bell-shaped curve interpretation B) calculated as part of the frequency distribution C) included in the range D) applicable when calculating the mode and median E) easily calculated when preparing a percentage frequency distribution 47) In the formula for calculating the standard deviation, the differences between each observation and the mean is squared. If we did not square these differences, the standard deviation would: A) be too small to be of any usefulness B) close to zero C) not be normally distributed D) not be interpreted by z values E) statistically insignificant 48) If a categorical question was being summarized, which analyses would be appropriate? A) mode and mean B) mode and range C) mean and frequency distribution D) mean and standard deviation E) mode and frequency or percentage distribution 49) When we square the standard deviation, the result is known as the: A) square of the standard deviation B) root of the standard deviation C) variance D) frequency distribution E) standard squared deviation 50) To ensure that their client managers understand the analysis terminology, ethical research companies use all of the following except: A) handbooks or glossaries defining marketing research terms B) appendices in reports that illustrate analysis concepts C) definitions of analysis terms embedded in reports D) footnotes or annotations with tables and figures that explain the analysis concepts used E) substitution of terms with those used by the client so that they feel comfortable with the level of language used
