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 http://people.hws.edu/halfman/Excel-07-demo/07-Error-Bars.html of data values is often represented by showing a single data point, representing the mean http://superuser.com/questions/339764/adding-standard-deviation-bars-in-excel-2007 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 error bars 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 standard error bars 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 crosses) that are very close to measurements taken at 20 degrees (shown in light green 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

I have 8 x-axis values, making a total of 16 actual bars. I need to add a different value of standard deviation for each bar (meaning 16 different values of standard deviation). How can I do this? How do I add the standard deviation for each bar if each standard deviation is different / unique for each bar? microsoft-excel standards share|improve this question edited Sep 26 '11 at 1:47 8088 12.3k113554 asked Sep 25 '11 at 23:11 Nelly 612 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote What you need is Error Bars share|improve this answer answered Sep 26 '11 at 1:32 chris neilsen 3,3731015 add a comment| You must log in to answer this question.
