This is the very convenient lifehack in Excel. After that, just to make double-click with the left mouse button and Excel will automatically fill empty cells with the formula and determine the range D2: D5, which must be filled to the cell D5 and no more. To copy the formula in the fastest way, you need just to move the mouse cursor to the cursor of the keyboard cursor (to the bottom right corner), so that the mouse cursor changes from the arrow to the black cross. You need to enter the formula in the cell D2 correctly with brackets, and then simply copy it to the other empty cells of the D2: D5 range. Closing the first part of the calculations in the brackets formula automatically raises the priority of the subtraction operation above with respect to the division operation. Such calculation (without parentheses) will be erroneous. Therefore, if we do not put parentheses, the first value will be divided, and then another value will be subtracted from it. By default in Excel, the division operation always has the highest priority with respect to the subtraction operation. It is important to pay attention to the presence of parentheses in this formula. The formula in the cell D2 calculates the percentage of deviation between the sales values for the current and last year: =(C2-B2)/B2 Pay attantion! If we swap the old and new numbers, then we have the formula for calculating the mark-up.Р В РІР‚СњР вЂ™Р’В«elow in the picture you can see the example, how the above calculation can be represented as the Excel formula. The formula is easy to verify: 120 + 25% = 150. In this example, the calculation formula is as follows (150-120) / 120 = 25%. The result of calculating this formula in Excel should be displayed in the percentage format of the cell. The percentage of deviation is calculated by subtracting the old value from the new value, and then dividing the result by the old one.

Final result: Standard error of meanР В РІР‚СњР В РІР‚С›s a result, the standard error of mean is 1.693, as calculated in cell E3.

Select cell E3 and enter the formula for SEM :Р В РІР‚СњР В РІР‚РЋigure 3.

COUNT function returns the number of data points in a sampleР В РІР‚СњР вЂ™Р’В«y using the above formula, we can calculate the standard error of mean through these steps:Р В РІР‚СњР В РІР‚РЋigure 2.

SQRT function returns the square root of a number.

STDEV.S function returns the standard deviation of a sample.

We can calculate the standard error of mean by using the functions STDEV.S, SQRT and COUNT. There is no built-in function that directly computes for the standard error of mean. Its formula is the quotient of standard deviation and the square root of sample size. SEM is not as popular as standard deviation, and it is sometimes just referred to as Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўstandard errorР В Р вЂ Р В РІР‚С™Р РЋРЎС™. It is an estimate of the deviation of a sample mean from the population mean. The Standard Error of Mean, also known as SEM is another measure of variability of data.
