What is the relationship between standard deviation and variance?Variance is the square root of standard deviationStandard deviation is the square of varianceStandard deviation and variance are not related to each otherStandard deviation is the square root of variance2. If data matches the normal distribution, the best measure of central tendency isMeanMoving rangeMedianIQR3. Six Sigma is referred to as:A statistical approach to problem solving3.4 defects per million opportunitiesA methodology, management systemAll the above4. Which of the following is NOT a lagging indicator?ToplineProfit after taxOn-going Six Sigma projectsEBITDA5. Specification limits may be given by:CustomersRegulatory bodiesResearch & Development teamAll of the above6. The appropriate graphical tools for displaying frequency distribution of discrete data are:Pareto plot, Bar graphHistogram, Bar graphPareto plot, HistogramHistogram, Scatter plot7. As sigma (standard deviation) ___________, sigma level_________ and DPMO __________.Increases, decreases, decreasesdecreases, decreases, increasesdecreases, decreases, decreasesNone of the above8. Six Sigma level corresponds to:0.0034 defects per billion opportunities3.4 defects per million opportunities3.4 parts per millionAll the above9. It normally takes me 30-40 minutes to commute to office daily. Note that it does not take me exactly 35 minutes each time because there is attribution of _______ variation.Special causeCommon causeRoot causeNone of the above10. In ___________ sampling there is high homogeneity within groups and high heterogeneity between groups.Stratified SamplingRandom SamplingSystematic SamplingCluster Sampling11. _________ is credited as the father of Six Sigma:Mikel HarryBill SmithBob GalvinLarry Bossidy12. __________ is used when the improvement made with ___________ are not enough.DMAIC, DMADVDMADV, IDOVIDOV, DMAICDMADV, DMAIC13. Which of the following is true?Boxplot displays the mean, Q3 and Q1 of the data setThe median will also be the mean, for a data that follows perfect normal distributionThe higher the variation the smaller is the Inter-quartile rangeThe median is always in the center of the box in a box plot14. What is the area contained within ± 3 standard deviations on either side of mean in a normal curve?68.26 %95.46 %99.73 %50 %Time is Up!
