error, or uncertainty in a reported measurement. They give a general idea of how precise a measurement is, or conversely, how far from the reported line graph error bars value the true (error free) value might be. Error bars often represent one bar graph error bars matlab standard deviation of uncertainty, one standard error, or a certain confidence interval (e.g., a 95% interval). These quantities are histogram error bars not the same and so the measure selected should be stated explicitly in the graph or supporting text. Error bars can be used to compare visually two quantities if various other conditions

hold. This can determine whether differences are statistically significant. Error bars can also suggest goodness of fit of a given function, i.e., how well the function describes the data. Scientific papers in the experimental sciences are expected to include error bars on all graphs, though the practice differs somewhat between sciences, and each journal will have its own house style. It has also been bar graph error bars r shown that error bars can be used as a direct manipulation interface for controlling probabilistic algorithms for approximate computation.[1] Error bars can also be expressed in a plus-minus sign (±), plus the upper limit of the error and minus the lower limit of the error.[2] See also[edit] Box plot Confidence interval Graphs Model selection Significant figures References[edit] ^ Sarkar, A; Blackwell, A; Jamnik, M; Spott, M (2015).

like this, building it up step by step. First, lets get the data file we will be using. use http://www.ats.ucla.edu/stat/stata/notes/hsb2, clear Now, let's use the collapse command to make the https://en.wikipedia.org/wiki/Error_bar mean and standard deviation by race and ses. collapse (mean) meanwrite= write (sd) sdwrite=write (count) n=write, by(race ses) Now, let's make the upper and lower values of the confidence interval. generate hiwrite = meanwrite + invttail(n-1,0.025)*(sdwrite / sqrt(n)) generate lowrite = meanwrite - invttail(n-1,0.025)*(sdwrite / sqrt(n)) Now we are ready to make a bar graph of the data The http://www.ats.ucla.edu/stat/stata/faq/barcap.htm graph bar command makes a pretty good bar graph. graph bar meanwrite, over(race) over(ses) We can make the graph look a bit prettier by adding the asyvars option as shown below. graph bar meanwrite, over(race) over(ses) asyvars But, this graph does not have the error bars in it. Unfortunately, as nice as the graph bar command is, it does not permit error bars. However, we can make a twoway graph that has error bars as shown below. Unfortunately, this graph is not as attractive as the graph from graph bar. graph twoway (bar meanwrite race) (rcap hiwrite lowrite race), by(ses) So, we have a conundrum. The graph bar command will make a lovely bar graph, but will not support error bars. The twoway bar command makes lovely error bars, but it does not resemble the nice graph that we liked from the graph bar command. However, we can finesse the twoway bar command to make a graph that resembles the graph bar command and then combine that with error bars. Here is a step by step proce

Which version do I have? More... Error bars express potential error amounts that are graphically relative to each data point or data marker in a data series. For example, you could show 5 percent positive and negative 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 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 series in the chart, click the chart area. To add error bars to a selected data point or data series, click the data point or data series that you want, or do the following to select it from a list of chart elements: Click anywhere in the chart. This displays the Chart Tools, adding the Design, Layout, and Format tabs. On the Format tab, in the Current Select
