What is the area of the semicircle (use 3.14 for and rho)?
That would depend on the radius which has not been given but the area of the semi circle will be (pi*radius squared)/2
Why is there a 6 in spearman rho formula?
The number 6 in the Spearman's rank correlation coefficient formula is a constant used to standardize the formula and make it more interpretable. It helps to scale the formula so that the resulting correlation coefficient falls within the range of -1 to 1, which indicates the strength and direction of the relationship between the ranked variables. Essentially, the 6 in the formula is a mathematical adjustment that ensures the correlation coefficient is properly calculated and comparable across different data sets.
A container holds 5 liters of water. What is the mass of the water in kilograms the density of water is 1.0gcm3?
m = dV (d for density (even though greek letter rho should be used))therefore m = (1.0 g/cm3)(5 L)m = (1.0 g/cm3)(5 dm3) (since 1 L = 1 dm3)m = (1.0 g/cm3)(5000 cm3) (since 1 dm3 = 1000 cm3)m = 5000 gm = 5 kg2,000 cm³
Spearman's rank correlation coefficient for three variables?
If what you're after is a simple solution in a statistical software, the quick answer is no. If your data dictates the use of nonparametric statistics (so you cannot use Pearson's), it may be an idea to try logistic regression instead.If, however, you're up for a challenge, there has been a recent (2010) paper exploring the possibility of using Kendall's tau, Spearman's rho and Spearman's footrule in multivariate analysis:Journal of Multivariate AnalysisVolume 101, Issue 10, November 2010, Pages 2398-2410Concordance measures for multivariate non-continuous random vectors by Mesfioui M and Quessy J-F.doi:10.1016/j.jmva.2010.06.011Good luck!
