PEARSON Search Chapter 12 Quiz: Nonparametric Measures of Correlation Question 9 of 15 Worth 5 Points What is one distinction between Goodman's and Kruskal's Gamma and Spearman's rank-order correlation coefficient? O Goodman's and Kruskal's Gamma requires ordinal-level data, while Spearman's rank-order correlation coefficient can use nominal-level data. O Goodman's and Kruskal's Gamma incorporates tied ranks, while Spearman's rank-order correlation coefficient ignores tied ranks O Goodman's and Kruskal's Gamma requires interval-level data, while Spearman's rank-order correlation coefficient can use ordinal-level data O Goodman's and Kruskal's Gamma ignores tied ranks, while Spearman's rank-order correlation coefficient incorporates tied ranks 1 attempt remaining the web and WindowsExplanation / Answer
Soution:
both are measures of ordinal categories.
Gamma statistic is utiized in cross tabulation tables
It is preferable to spearman R whenthe data contain many tied observations.Gamma is a probability ;specifically it is computed as difference between the probability that the rank ordering of the two variables agree minus probbaility that they disagree divided by 1 minus the probability of ties.
