earlier, just as you did when taking the average. Hit enter, and “OK” to calculate the standard deviation. 4. With the cursor still on the same cell, now click in the formula bar at the standard error excel formula top of the spreadsheet (the white box next to the “=” sign) to put the cursor in that bar so you can edit the formula. 5. Put a “(“ in front of STDEV and a “)” at the end of the formula. Add a “/” sign to indicated you are dividing this standard deviation. Put 2 sets of parentheses “(())” after the division symbol. Put the cursor in the how to calculate standard error from standard deviation middle of the inner set of parentheses. 6. Now click on the fx symbol again. Choose “Statistical” on the left hand menu, and then “COUNT” on the right hand menu. 7. Click on the spreadsheet picture in the pop-up box, and then highlight the list of numbers you averaged. Hit enter and “OK” as before. 8. Move the cursor to be between the 2 sets of parentheses, and type “SQRT”. Hit enter. The standard error of the mean should now show in the cell. Your formula in the formula bar should look something like this, “=(STDEV(A1:A2))/(SQRT(COUNT(A1:A2)))”. (This formula would calculate the standard error of the mean for numbers in cells A1 to A2.) NOTE: We have calculated standard error of the mean by dividing the standard deviation of the mean by the square root of n. Given the formula that Excel uses for calculation of standard deviation of the mean, this gives the standard error of the mean after adjusting for a small sample size. This is usually the case in physiology experiments. The formula would be different with a very large sample size. I do not know why Excel still does not include a formula for calculating the standard error of the mean.

the completed graph should look something like: Create standard error your bar chart using the means as the bar heights. Then, right click on any of the bars and choose Format Data Series. Click how to calculate on the Y-Error Bars tab, Choose to display Both error bars, and enter the ranges for standard errors (cells C15:E15 in the example above) in the Custom Error amount. Be sure to both add and subtract the standard errors (C15:E15 ) in the custom amount. The dialog box should look like: Click OK and the graph should be complete. Be sure to add a title, data source, and label the axes.
Though no one of these measurements are likely to be more precise than any other, this group of values, it is hoped, will cluster about the true value you are trying to measure. This distribution of data values is often represented by showing a single data point, representing the mean value of the data, and error bars to represent the overall distribution of the data. Let's take, for example, the impact energy absorbed by a metal at various temperatures. In this case, the temperature of the metal is the independent variable being manipulated by the researcher and the amount of energy absorbed is the dependent variable being recorded. Because there is not perfect precision in recording this absorbed energy, five different metal bars are tested at each temperature level. The resulting data (and graph) might look like this: For clarity, the data for each level of the independent variable (temperature) has been plotted on the scatter plot in a different color and symbol. Notice the range of energy values recorded at each of the temperatures. At -195 degrees, the energy values (shown in blue diamonds) all hover around 0 joules. On the other hand, at both 0 and 20 degrees, the values range quite a bit. In fact, there are a number of measurements at 0 degrees (shown in purple squares) that are very close to measurements taken at 20 degrees (shown in light blue triangles). These ranges in values represent the uncertainty in our measurement. Can we say there is any difference in energy level at 0 and 20 degrees? One way to do this is to use the descriptive statistic, mean. The mean, or average, of a group of values describes a middle point, or central tendency, about which data points vary. Without going into detail, the mean is a way of summarizing a group of data and stating a best guess at what the true value of the dependent variable value is for that independent variable level. In this example, it would be a best guess at what the true energy level was for a given temperature. The above scatter plot can be transformed into a line graph showing the mean energy values: Note that instead of creating a graph using all of the raw data, now only the mean value is plotted for impact energy. The mean was calculated for each temperature by using the AVERAGE function in Excel. You use this function by typing =AVERAGE in the formula bar and then putting the range of cells containing the data you want the mean of within parentheses after the function name, like this: In thi
