    Thanks for reaching out to us with your problem.
    This problem occurs when you do not have enough view area on the monitor. While there is no particular fix to your problem, if you want to keep the cell styles in the Ribbon, you may consider removing some unnecessary groups from the Home tab.

    To do so follow these steps:
    1. Right-click on the empty area of the Ribbon.
    2. Select “Customize the Ribbon“.
    customize the ribbon
    3. From the Home tab dropdown, select and remove unnecessary groups one by one.
    4. Click on OK to finish the process.
    removing groups from the home tab

    After removing the groups, cell styles will be visible without the “Cell Styles” drop-down if there is enough room in the Ribbon.

    Dear AVI,
    We can assure you that if you followed the steps correctly, everything should be fine with the tutorial. Moreover, both of these formulas are single-cell output formula. So, the procedure for the array formula implementation or pressing CTRL+SHIFT+ENTER is not required here.
    If you want to take all the data to find out the standard deviation without conditions or avoid taking the false as 0, you should have a look at our article How to Calculate Average and Standard Deviation in Excel.

    Dear Fardeen,

    The profit margin is the percentage you get from the selling price. The formula for profit margin is: (Selling Price-Cost Price)/Selling Price or, Net Profit/Selling Price

    The profit margin is calculated in the worksheet with the formula: =(F5-E5)/F5

    On the other hand, the profit percentage is calculated based on the Cost Price. The formula for profit percentage is: (Selling Price-Cost Price)/Cost Price or, Net Profit/Cost Price

    The profit percentage is calculated in the worksheet with the formula: =(F5-E5)/E5
