Which function would you use to find the highest value in a range of cells?

The function used to find the highest value in a range of cells in Excel is MAX(). This function specifically evaluates the numerical values within the specified range and returns the largest one. When dealing with datasets where you want to identify the maximum performance, score, measurement, or any numerical maxima, MAX() is the appropriate choice.

For example, if you have a series of sales figures in a range and want to determine the highest sales amount, you would use MAX() to quickly retrieve that value. This function is straightforward and is optimized for the task of identifying the largest number, making it a fundamental tool in Excel for data analysis and reporting. The other options serve different purposes: MIN() finds the smallest value, AVERAGE() calculates the mean of the numbers, and COUNT() is used to count how many cells contain numeric data. Each has its own function, but for finding the highest value specifically, MAX() is the correct answer.
