QUESTION 1 The measurement scale that allocates values to variables based on their relative ranking with respect to one another in a given data set, but which does not specifically quantify the magnitude between successive ranks, is Oordinal scale O nominal scale Oratio scale O interval scale QUESTION 2 Which statements are CORRECT? An automobile insurance agent believes that company "A" is more reliable than company "B". The scale of measurement that this information represents is the ordinal scale. In a histogram, each observation is assigned to one or more classes. The sum of cumulative relative frequencies always equals 100%. A relative frequency distribution describes the proportion of data values that fall within each category. A bar chart is only used to represent ordinal or interval data. QUESTION 3 Which statements are INCORRECT? The range is considered the weakest measure of variability. The number of standard deviations between the 25th percentile and the median is always the same as between the median and the 75th percentile. The 5-number summary consists of the smallest observation, the first quartile, the median, the third quartile, and the largest observation. If two data sets have the same standard deviation, they must have the same coefficient of variation.

QUESTION 1 The measurement scale that allocates values to variables based on their relative ranking with respect to one another in a given data set, but which does not specifically quantify the magnitude between successive ranks, is O ordinal scale O nominal scale Oratio scale O interval scale QUESTION 2 Which statements are CORRECT? An automobile insurance agent believes that company "A" is more reliable than company "B". The scale of measurement that this information represents is the ordinal scale. ☐ In a histogram, each observation is assigned to one or more classes. The sum of cumulative relative frequencies always equals 100%. A relative frequency distribution describes the proportion of data values that fall within each category. A bar chart is only used to represent ordinal or interval data. QUESTION 3 Which statements are INCORRECT? The range considered the weakest measure of variability. The number of standard deviations between the 25th percentile and the median is always the same as between the median and the 75th percentile.
