To determine variability in his data, Jar Jar Binks calculated variance O No, variance determines variability in squared differences O Yes, variance does not provide infor mation about the variability in the data O Yes, he should have just relied on the average for the variability O No, variance compounds errors in variability and the cumulative error explains a higher variance number QUESTION S Looking at the sales and marketing expenditure data, an analyst realizes that despite increasing the marketing expenditure on one product, the sales of that product did not increase. if the analyst was to compute a correlation, what be the expected correlation coefficient Corelation coefficient close to-1 O Corelation coeficient close to onmega Correlation coefficient close to zero O Conelation coefficient close to+
