Which function would you use to summarize a range of data by its most frequently occurring value?

The function used to summarize a range of data by its most frequently occurring value is MODE.SNGL(). This function identifies and returns the mode of a dataset, which is the value that appears most frequently. When analyzing data, understanding the most common value can provide significant insights, especially in areas like statistics and data analysis.

MODE.SNGL() is particularly useful because it can handle situations where there are multiple modes; however, it will only return the first mode it encounters. This makes it a straightforward and effective choice when the goal is to find the most repeated value in a list or range of data.

The other functions presented serve different purposes and are not relevant for identifying a mode. For example, COUNT() is used to count the number of cells that contain numeric values, while SUM() totals a range of numbers. The CELL() function provides information about the formatting, location, or contents of a cell but does not perform any statistical analysis. Thus, MODE.SNGL() stands out clearly as the most appropriate function for summarizing data by its most frequently occurring value.
