Central Tendency QuizVersion en ligne Measures of center par Aimie Del Rosario 1 Which measure of central tendency is most affected by outliers? a Median b Mode c Geometric mean d Mean 2 What is the median of the data set: 3, 7, 7, 2, 9? a 2 b 9 c 7 d 3 3 Which measure is most appropriate for skewed data? a Geometric mean b Mean c Median d Mode 4 If a data set is 4, 4, 6, 6, 6, the mode is: a 4 b 5 c None d 6 5 Which statement about the mean is true? a It is always the middle value. b It is the arithmetic average. c It is unaffected by outliers. d It is the most frequent value. 6 What is a trimmed mean? a Average of the two middle values b Mode after removing all duplicates c Mean of only the top half values d Mean after removing extreme values 7 Which measure combines values with weights to reflect importance? a Geometric mean b Median c Weighted mean d Mode 8 Which is true about the geometric mean? a Used for data with multiplicative effects b Used for categorical data c Insensitive to zeros in data d Always largest of the three measures 9 In a symmetric distribution, which two measures of central tendency are equal? a Median and mode b Geometric mean and mean c Mean and median d Mode and mean 10 A data set has outliers: 1, 2, 2, 2, 100. Which measure best represents typical value? a Mean b Mode c Geometric mean d Median Feedback 1 Outliers pull the mean toward them more than the median or mode. 2 The middle value after ordering: 2,3,7,7,9; the median is 7. 3 Median resists extreme values in skewed data. 4 The value appearing most frequently is 6. 5 Mean equals the sum divided by count; it can be skewed by outliers. 6 Trimmed mean reduces outlier influence by cutting extremes. 7 Weights adjust each value's influence on the average. 8 Geometric mean suits growth rates; zeros break calculation. 9 Symmetry makes mean and median coincide. 10 Median ignores extreme value 100, unlike the mean.
