Pegasystems PEGAPCDC87V1 Exam - Topic 6 Question 30 Discussion

Actual exam question for Pegasystems's PEGAPCDC87V1 exam

Question #: 30
Topic #: 6

U+, a retail bank, recently implemented a project in which credit card offers are presented to qualified customers when they log in to the web self-service portal. The bank does not want any bias except to satisfy the eligibility condition Age >=18. As a Decisioning Consultant, how will you configure the ethical bias policy to allow a minimum bias on age?

A0 Gini

B0.7 Gini

CNo Detection

D0.1 Gini

Show Suggested Answer

Suggested Answer: D

Ethical Bias Policy Configuration:

To allow minimal bias on age while ensuring eligibility (Age >= 18), an appropriate Gini coefficient threshold needs to be set.

The Gini coefficient measures statistical inequality, with 0 representing perfect equality and higher values indicating more bias.

Choosing the Gini Threshold:

A 0.1 Gini coefficient is a low threshold that allows minimal bias.

It ensures that the actions are distributed fairly among customers while still respecting the eligibility condition.

Detailed Explanation:

Setting a 0.1 Gini coefficient allows for slight variations in distribution, which is sufficient to accommodate the Age >= 18 requirement without introducing significant bias.

Verification from Pega Documentation:

The Pega Customer Decision Hub User Guide explains the use of Gini coefficients for measuring and setting thresholds to control bias in decisioning strategies.

Wait, does 0.7 Gini really mean less bias? I'm not so sure.

No Detection? That seems risky, how can you ensure fairness?

Why even bother with age if we're just looking at eligibility?

0 Gini sounds too extreme, might miss out on good offers.

I think 0.1 Gini is the way to go for minimal bias.

I vaguely remember that a Gini of 0.1 could suggest minimal bias, but I’m not completely confident about that.

I feel like "No Detection" might be the safest option, but it seems too vague for this scenario.

I think we practiced a similar question where a lower Gini meant less bias, but I can't recall the exact numbers we used.

I remember discussing Gini coefficients in class, but I'm not sure which value indicates minimal bias.

This is a tricky one. I'm not entirely sure how to interpret the Gini coefficient values and their impact on bias. I'll need to think through this carefully and maybe even sketch out a few examples to see how the different options would play out. Definitely going to spend some extra time on this question.

Okay, I think I've got this. The bank wants to minimize bias except for the age requirement, so we need to choose the option that has the lowest Gini coefficient while still allowing the age check. That would be option D, 0.1 Gini.

Hmm, I'm a bit confused by the different Gini coefficient options. I'll need to review my notes on how Gini coefficients work and what the different values mean in terms of bias. Maybe I can ask the instructor for some clarification during the break.

This question seems straightforward - we need to configure the ethical bias policy to allow a minimum bias on age. I think option D, 0.1 Gini, is the best choice since it minimizes bias while still satisfying the eligibility condition.
