Question 1 of 30
A data scientist is evaluating the performance of a machine learning model using cross-validation techniques. They decide to implement k-fold cross-validation with k set to 10. After running the model, they observe that the average accuracy across the 10 folds is 85%, with a standard deviation of 5%. If the data scientist wants to assess the reliability of this model\'s performance, which statistical measure should they consider to understand the variability of the model\'s accuracy across the folds?
The standard deviation of the accuracy scores
The mean accuracy of the folds
The maximum accuracy achieved in any fold
The minimum accuracy achieved in any fold
