Suppose that cells B1 through B100 of an Excel spreadsheet contain the quantity of units ordered on each of 100 different days.
The Excel function that would count the number of cells that contain quantities of at least 50 is a. =COUNTIF(B1:B100,">=50") b. =COUNTIF(B1:B100,>=50) c. =COUNTIF(B1:B100,>50) d. =COUNTIF(B1:B100,">50")
The "COUNTIF" function counts every cell that, given a condition (value), suits into it. As you want to know the number of cells that contain a value of at least 50, the condition must be properly written to get the correct answer. Unless it is a cell value (e.g. B3), the condition must always be written with quotes (""). So, the options b and c are automatically discarded.
The d option appears to be correct, but it's not. If the condition is written ">50", the function will count every cell with a value above 50. But we're searching values at least (including) 50. So the correct answer is the a option.
