To change the vertical axis scale, click the vertical axis and right click. Select Median-Q1 the portion that now appears to be the lower part of each column , right-click and pick Format Data Series from the pop-up menu.
There are a couple ways around this problem and both of these alternate methods are included as additional worksheets in the file. The area property is set to none for these two series to create just the outline for the box. It lets you create a Box Plot, Waterfall, or other complex charts with just a few clicks. So… if you are performing a quartile calculation utilizing Excel data from a prior version e.
8 Box and Whisker Plot Excel 2010 Template - The values were taken from a normally distributed population with a mean of 10 and standard deviation of 5. With this range selected, insert a stacked column chart or a stacked bar chart.
Instead, you can cajole a type of Excel chart into boxes and whiskers. Instead of showing the , the box-and-whisker plot shows the minimum, first quartile, median, third quartile, and maximum of a set of data. Statisticians refer to this set of statistics as a five-number summary. The median divides the box. How you lay out the chart determines the width of the box. The whiskers are error bars: One extends upward from the third quartile to the maximum, and the other extends downward from the first quartile to the minimum. The first order of business is to put data into a worksheet and start computing some statistics. The following figure shows the worksheet and the statistics. The next group of statistics holds the values for the five-number summary. You can use MIN to find the minimum value for each year, and MAX to find the maximum value. INC computes the first quartile and the third quartile. Not surprisingly, MEDIAN determines the median. The final group of statistics holds the values you put directly into the box-and-whisker plot. Why is this group necessary? You can turn a Stacked Column chart into a box-and-whisker plot. In a box-and-whisker box, however, the size of a segment represents a difference between one value and another — like the difference between the quartile and the median, or between the median and the first quartile. So the box is really a stacked column with three segments. The first segment is the first quartile. The second is the difference between the median and the first quartile. The third is the difference between the third quartile and the median. Not after you make the first segment disappear! The other two differences — between the maximum and the third quartile and between the first quartile and the minimum— become the whiskers. The fourth option in the Recommended Charts is also a stacked column chart. Its rows and columns are reversed. The figure also shows the chart toolset to right of the chart. First, add the lower whiskers. With the bars corresponding to Q1 selected the lowest portion of each stacked column , click the Plus Sign in the chart toolset. From the pop-up menu that appears, select the Error Bars check box, and then the arrowhead to the right of that option. From the resulting menu, select More Options. This opens the Format Error Bars panel. Select the Minus radio button, the Cap radio button, and the Custom radio button. Then click the Specify Value button to open the Custom Error Bars dialog box. Leaving the Positive Error Value as is, specify the cell range for the Negative Error Value. Follow similar steps to add the upper whiskers. This time select the part of the stacked columns corresponding to Q3-Median the upper portion of each stacked column. Then as earlier, click the Plus Sign in the chart toolset. Again, select the box next to Error Bars in the pop-up menu, and the arrowhead to the right of that option. This time in the Format Error Bars panel, select the Plus radio button, the Cap radio button, and the Custom radio button. Again, click the Specify Value button to open the Custom Error Bars dialog box. This time, specify the cell range for the Positive Error Value. That cell range is B24:D24 Max-Q3. Click OK and Close. To give the appearance of boxes rather than stacked columns, select Q1 the bottom portion of each column , then right-click and choose Format Data Series from the pop-up menu to open the Format Data Series dialog box. In the Format Data Series panel, click Fill the bucket icon , and in the Fill area select the No Fill radio button. Then in the Border area, select the No Line radio button. Clicking Close closes the Format Data Series panel. Select Median-Q1 the portion that now appears to be the lower part of each column , right-click and pick Format Data Series from the pop-up menu. In the Format Data Series panel, select Fill and select the No Fill radio button in the Fill area. Then select the Solid Line radio button in the Border area. Next select Border Color and select the Solid Line radio button. Click the Color Button and select black from the Theme Colors palette. Finally, select Q3-Median the upper portion of each column , and then go through the same sequence. After that, delete the legend. You can add another data series that shows where the means are, and another that would allow me to connect the medians, but this is enough for now. Notice that after you finish working with the Format Data Series panel for one data series, you can leave it open. Then select another data series in the chart and start formatting it.
Click the spreadsheet icon. You also risk distorting the future use of box plots by those who are not yet familiar with them. A panel is going to be difficult to construct, but you could show two charts side by side. Warriner, whenever I try to create my graph I get an error message. The questionnaire scores from these groups are summarized in Figure 1. You can see how the utility works in this. Your browser can't show this frame. Do not change this or the graph will be wrong. Delete the contents of the Negative Error Value box in the mini dialog that appears, then clear the Positive Error Value box and select the Whisker+ row from the table B15:E15.
