Rumsey When a research question asks you to find a statistical sample mean (or average), you need to report a margin of error, or MOE, for the sample mean. The general formula for the margin http://www.dummies.com/education/math/statistics/how-to-calculate-the-margin-of-error-for-a-sample-mean/ of error for the sample mean (assuming a certain condition is met -- see below) is is the population standard deviation, n is the sample size, and z* is the appropriate z*-value for your desired level of confidence (which you can find in the following table). z*-Values for Selected (Percentage) Confidence Levels Percentage Confidence z*-Value 80 1.28 90 1.645 95 1.96 98 2.33 99 2.58 Note that these values are taken from the standard normal (Z-) distribution. The area between each z* value and the negative of that z* value is the confidence percentage (approximately). For example, the area between z*=1.28 and z=-1.28 is approximately 0.80. This chart can be expanded to other confidence percentages as well. The chart shows only the confidence percentages most commonly used. Here are the steps for calculating the margin of error for a sample mean: Find the population standard deviation and the sample size, n. The population standard deviation, will be given in the problem. Divide the population standar

Excel It would be nice if all data was perfect, absolute and complete. But when it isn't, Excel gives us some useful tools to convey margins of error and standard deviations. If you work in a field that needs to reflect an accurate range of data error, then follow the steps below to add Error Bars to your charts and graphs: Begin by creating your spreadsheet and generating the chart or graph you will be working with. To follow using our example below, download Standard Deviation Excel Graphs Template1 and use Sheet 1. These steps will apply to Excel 2013. Images were taken using Excel 2013 on the Windows 7 OS. 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. 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. To find and turn on Error Bars in Excel 2007-2010, select the chart, then click the Error Bars dropdown menu in the Layout tab under the Chart Tools contextual tab. Customize Error Bar Settings To customize your Error Bar settings, click More Options to open the Format Error Bars Task Pane. To follow using our example, download the Standard Deviation Excel Graphs Template1
