Inat Is Il olne eXISIS. Choose: O 84 083 O 60 O no outliers (b) What is the mean for this set of data? O 75 Choose: O 77.6 O 78.9 O 79.5 2 of 3 Choose: (c) What is the mean for this set of data, if the outlier is removed? o 77.6 O 75 o 78.9 o 79.5 (d) Which of the box plots gives the best representation of this data set? Choose: o Box A о Вох В o Both give the same information. Box B O Neither represent this data. Box A . Mu com 50 60 70 80 3. The data set shown below has an outlier. Determine the outlier and then answer the questions as to what happens to the median, mean, mode, range and standard deviation when the outlier is removed. Data: 29, 19, 35, 27, 21, 48, 23, 12, 24, 26, 20, 28, 30, 22, 19, 32, 22 If the outlier is excluded, what happens to: Increase Decrease No effect the median? the mean? the mode? the range? the standard deviation? 4. Which measure of central tendency is most affected by outliers? Choose: O mean O median O mode 5. Carlos recorded his friends' scores while playing the video game "Golden Eye Commander". Most of his friends' scores were between 9 and 12. One score, however, was 28, and Carlos identified it as an outlier. What should Carlos do with the score of 28 when recording this data? Choose: O Ignore the outlier since it is so far from the average scores. O Ignore the outlier because he may have recorded the score incorrectly. O Eliminate the outlier and ask that friend to play again to obtain a new score. O Keep the outlier as it may help to explain a new strategy for playing the game. H 6. Given the box plot: 12 14 1 20 (a) What is the first quartile, Q1. value? 05 Choose: 08 O 14 16 hhWhot ic the third O ualua?
