Which of the following statements are true about the Gini index (GI)? Assume a binary classification problem where all instances are labeled as positive or negative.

How is the Gini index used in the context of a decision tree?To determine the splitting attributeTo determine the depth of the treeTo determine the leaf node valuesTo prune the tree branches

In a decision tree used to predict whether a stocks will have a "good" or a "bad" return, the Gini Impurity coefficient is:Group of answer choiceshigher if a node has a similar number of good and bad stocks.lower if a node has a similar number of good and bad stocks.lower if a node has many stocks.higher if a node has many stocks.

The Gini coefficient in a perfectly unequal society will have a Gini coefficient of _____,  while a perfectly equal society will have a Gini coefficient equal to _____.Group of answer choices0 and 1infinity and 0−1 and 11 and 00 and infinity

Based on the information in the map, determine the appropriate labels for each location. The GINI Index measures economic inequality: inequality is higher the closer to 1 the GINI coefficient is.
