2. Suppose the numbers given bellow are the percentage of elligible voters who actually voted during the national election (voter turnout) in 100 precincts randomly sampled in the province of Albay. 4.8% 13.3% 19.3% 22.4% 24.3% 25.1% 27.3% 36.0% 39.5% 46.8% 4.8 13.4 19.3 22.4 25.1 27.3 27.3 36.3 39.5 46.8 9.3 15.1 20.7 22.4 25.1 27.3 32.3 36.3 39.5 46.8 9.3 15.1 20.7 22.4 25.1 27.3 33.0 36.3 41.0 47.1 9.3 15.1 21.6 24.3 25.1 27.3 33.1 37.1 43.7 49.6 10.3 15.1 21.6 24.3 25.1 27.3 33.4 37.1 43.7 53.5 10.3 17.8 21.6 24.3 25.1 27.3 33.4 37.1 43.7 58.1 10.3 17.8 21.6 24.3 25.1 27.3 33.6 37.1 44.3 84.0 12.3 17.8 22.4 24.3 25.1 27.3 33.6 37.9 45.5 84.0 13.3 19.3 22.4 24.3 25.1 27.3 35.1 37.9 46.1 84.0 a. Compute for the mean, median and mode of this data. b. Compute also for the Range, SD and variance. c. Trim down the data by 10% (delete bottom 5% and top 5% ) then compute for the same measures of central tendency and variation. Compare the new computed values of measures with the original.
