Which function would help Mrs. Michaud compile a list of assessed standards effectively?

The function that will most effectively help Mrs. Michaud compile a list of assessed standards is the function that retrieves unique values from a designated column. This means that when applied to a column where assessed standards are listed, it will only return each standard once, eliminating duplicates. This way, Mrs. Michaud can easily see what standards have been assessed without having to sort through a long list that may contain repeated entries. Utilizing this function allows for a clearer and more efficient overview of the actual standards being addressed.

In contrast, the other functions serve different purposes that may not meet her specific need for compiling a list of standards. The summation function would total numerical values in a column, which doesn't align with the goal of listing standards. The counting function would only provide the total count of entries, not distinguishing between unique standards. Similarly, the averaging function calculates the mean of numerical values in a column, which also does not help in listing or distinguishing the assessed standards effectively. Therefore, the unique function is indeed the most suitable choice for the task at hand.
