Which of the following functions returns all mode values from a dataset?

The function that returns all mode values from a dataset is the one labeled as "Mode multiple." This function is designed to identify and return every mode present in the dataset, which is particularly useful when there are multiple values that occur with the highest frequency. Unlike "Mode single," which only reports the first mode found and cannot provide information on multiple modes, "Mode multiple" effectively captures the entire set of modes, enabling a comprehensive understanding of the dataset's frequency distribution.

Median and mean absolute percentage deviation are statistical measures that serve completely different purposes and do not relate to identifying modes. The median is the middle value of a dataset when arranged in order, providing insight into the central tendency of the data. Meanwhile, mean absolute percentage deviation measures prediction accuracy by assessing how much the predicted values deviate from actual values in percentage terms. Therefore, both of these options are not relevant for the purpose of identifying mode values, further clarifying why "Mode multiple" is the correct choice in this context.
