each data point or data marker in a data series. For example, you could show 5 percent positive and negative excel 2007 error bar plot potential error amounts in the results of a scientific experiment: You can add error bars to data series in a 2-D area, bar, column, line, xy (scatter), and bubble charts. For xy (scatter) and

bubble charts, you can display error bars for the x values, the y values, or both. After you add error bars to a chart, you can change the display and error amount options of the error bars as needed. You can also remove error bars. What do you want to do? Review equations for calculating error amounts Add error bars Change the display of error bars Change error bars scatter plot excel the error amount options Remove error bars Review equations for calculating error amounts In Excel, you can display error bars that use a standard error amount, a percentage of the value (5%), or a standard deviation. Standard Error and Standard Deviation use the following equations to calculate the error amounts that are shown on the chart. This option Uses this equation Where Standard Error s = series number i = point number in series s m = number of series for point y in chart n = number of points in each series yis = data value of series s and the ith point ny = total number of data values in all series Standard Deviation s = series number i = point number in series s m = number of series for point y in chart n = number of points in each series yis = data value of series s and the ith point ny = total number of data values in all series M = arithmetic mean Top of Page Add error bars On 2-D area, bar, column, line, xy (scatter), or bubble chart, do one of the following: To add error bars to all data

Click on the chart, then click the Chart Elements Button to open the fly-out list of checkboxes. Put a check in the Error Bars checkbox. Click the arrow beside the Error Bars checkbox to choose from common error types: Standard Error – Displays standard error amount for all values. Percentage – Specify a percentage error range and Excel will calculate the error amount for each value. http://www.pryor.com/blog/add-error-bars-and-standard-deviations-to-excel-graphs/ Default percentage is 5%. Standard Deviation – Displays standard deviation error amount for all values. Resulting X &Y error bars will be the same size and won't vary with each value. You can also turn on Error bars from the Add Chart Element dropdown button on the Design tab under the Chart Tools contextual tab. Blast from the Past: Error Bars function similarly in Excel 2007-2010, but their location in the user interface changed in 2013.

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 form
