Question 10A data analyst creates two different predictive models for the same dataset. They use the bias() function on both models. The first model has a bias of -40. The second model has a bias of 1. Which model is less biased?

Which of the following statements regarding model estimation bias and variance is false?Group of answer choicesEstimation bias typically is caused by small sample sizes.ML algorithms with more model complexity tend to have higher estimation variance.High estimation bias is when an ML algorithm can’t fit the true pattern, leading to underfitting.Model estimation variance can be reduced by adding more data or averaging different models.

Which of the following is NOT a common decision-making bias that can affect choice activities?Question 28Answera.Availability biasb.Unanimity biasc.Confirmation biasd.Anchoring bias
