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 value the true (error free) value error bars in excel 2015 might be. Error bars often represent one standard deviation of uncertainty, one standard error, or a certain confidence error bars in excel 2007 interval (e.g., a 95% interval). These quantities are 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 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).

chart Editing charts Formatting charts Formatting 3D charts Formatting chart elements Resizing and moving the chart Gallery of chart types < Previous Page Next Page > After you have created a chart, you may find things you https://wiki.openoffice.org/wiki/Documentation/OOo3_User_Guides/Calc_Guide/Editing_charts would like to change. Calc provides tools for changing the chart type, chart elements, data ranges, fonts, colors, and many other options, through the Insert and Format menus, the right-click (context) menu, and the Chart toolbar. Contents 1 Changing the chart type 2 Adding or removing chart elements 2.1 Data labels 2.2 Trend lines 2.3 Mean value lines 2.4 Y error bars Changing the chart type You can change the chart type at any error bars time. To do so: First select the chart by double-clicking on it. The chart should now be surrounded by a gray border. Then do one of the following: Choose Format > Chart Type from the menu bar. Click the chart type icon on the Formatting toolbar. Right-click on the chart and choose Chart Type. In each case, a dialog similar to the one in Choosing a chart type opens. Adding or removing chart error bars in elements The figures below show the elements of 2D and 3D charts. The default 2D chart includes only two of these elements: Chart wall contains the graphic of the chart displaying the data. Chart area is the area surrounding the chart graphic. The (optional) chart title and the legend (key) are in the chart area. The default 3D chart also has the chart floor, which is not available in 2D charts. Elements of 2D chart Elements of 3D chart You can add other elements using the Insert menu. The various choices open dialogs in which you can specify details. First select the chart so the green sizing handles are visible. This is done with a single click on the chart. The dialogs for Title, Legend, Axes, and Grids are self-explanatory. The others are a bit more complicated, so we’ll take a look at them here. Data labels Data labels put information about each data point on the chart. They can be very useful for presenting detailed information, but you need to be careful to not create a chart that is too cluttered to read. Choose Insert > Data Labels. Data Labels dialog The options are as follows. Show value as number Displays the numeric values of the data points. When selected, this option activates the Number format button. Num
