1 Statistical Analysis Using Gnumeric There are many software packages that will analyse data. For casual analysis, a spreadsheet may be an appropriate tool. Popular spreadsheets include Microsoft Excel, LibreOffice Calc, and Gnumeric. While most operations below can be carried out using any spreadsheet, they often lack certain features. Excel, for example, has no native box-and-whisker plot capabilities. Gnumeric, however, has a wide range of statistical analysis tools built into it. Gnumeric is free software, and runs on multiple operating systems. You can download Gnumeric at You can even download a portable version that you can run off of a USB drive from Entering Data and Calculating Values When you first start Gnumeric, the main screen will look something like this. Initial screen after starting Gnumeric The area is divided into a rectangular grid of cells. Each cell has a reference made up of its column letter and row number. For example, the reference of the active cell in the screenshot above is A1. Data can be entered by typing in a value or a formula in a cell. Typically, data from each variable is entered downward in columns rather than across in rows. A descriptive column header is recommended, so that it is clear what the data represent. A simple example is shown on the following page.

2 Using a formula with cell references Formulae may be entered in the formula box, next to the equals sign at the top of the screen, or directly in an empty cell. All formulae begin with =, to indicate that they should be evaluated. Formulae may use values, cell references and mathematical operators in them. In the screenshot above, the value of 9 in cell B4 is the square of the value of 3 in A4, and was calculated using the formula =A4^2. Cell references are encouraged, since all calculations based on the value of a referenced cell will update if the value is updated. In addition to mathematical operators, functions can also be used in formulae. Common functions are sum() to add a range of values, average() to calculate the mean, median() to find the central datum in a set, and so on. See the Help menu option to discover the full range of functions available.

3 Obtaining Basic Statistics About Data Assume that the following sample of ages of various players of an online game has been entered. A simple sample of 15 ages It is possible to calculate different statistics by using Gnumeric's functions. For example, the standard deviation of the sample can be calculated using =stdev(a2:a16), or the mode using =mode(a2:a16). While effective, there is a better method. A quick way to calculate basic statistics is to select Statistics Descriptive Statistics Descriptive Statistics from the main menu. This calculates common measures of central tendency (mean, median and mode) and measures of spread (standard deviation and variance) for a sample. Doing this with the earlier data produces the following information on a separate sheet.

4 Generating common statistics Statistics that are not of interest (such as kurtosis, skewness, or standard error) can be deleted by right-clicking a row number and selecting Delete Row. Deleting a row of data

5 Additional statistics, including the first and third quartiles and the interquartile range, must be calculated manually. To calculate the first quartile, enter the label Q1 in cell A12, and enter the following formula in cell B12: =quartile(sheet1!a2:a16,1). In this formula, Sheet1! refers to the data on Sheet1 of the workbook, A2:A16 specifies the cells containing the data, and 1 refers to the first quartile. The result is shown below. The third quartile can be calculated in the same way, using 3 in place of 1. This is shown in row 13. Calculating additional measures of spread The interquartile range is the range of the data between the first and third quartiles. In cell B14, the formula =B13-B12 was used. The semi-interquartile range is half the value of the interquartile range, and is calculated using =B14/2. Besides calculating values of common measures of central tendency or spread, it is possible to create various types of graphs. The next few sections describe how to create box-and-whisker plots and histograms for single-variable data.

6 Creating Box-and-Whisker Plots To create a box-and-whisker plot for single-variable data, enter the data in a column and select the values (not including the column header) using either the mouse of the shift key. Selecting data to plot Select Insert Chart from the main menu, or click the Insert Chart icon on the menu bar. This will bring up a dialogue box with various options. Select Statistics and you should see four types of box-and-whisker plots: both standard modified box-and-whisker plots, in both horizontal or vertical orientations. Creating a modified box-and-whisker plot

7 The mouse cursor should change from an arrow to cross-hairs, allowing you to select where on your sheet you would like to place the graph. Click anywhere on the sheet to create the plot. The appearance of a box-and-whisker plot can be changed by right-clicking on the plot and selecting Properties. For example, to remove the default grey background, click Backplane, and change the Fill Type to None. Changing the background colour To create a title for the box-and-whisker plot, click Chart1 in the list. Click the Add button, then select Add Title as shown below. Similarly, a label can be added to the x-axis by selecting X-Axis, then the Add button, then Label. Adding a title

8 The label on the y-axis is meaningless, and may be removed by selecting Y-Axis from the list, then unchecking Show Label from the Layout tab. Removing the y-axis label The final product is displayed below. A modified box-and-whisker plot showing the ages of players

9 Creating Histograms and Frequency Polygons A histogram is similar to a bar chart, where the area of each bar is equal to the frequency of all data in a given interval, and the height of each bar is equal to the interval frequency divided by its width. It may, however, be easier to visualize data when the height of each bar corresponds directly to its frequency. The procedure below produces a hybrid histogram/bar chart with this property instead. Before generating a frequency table to use with our histogram, create two columns. The first column will correspond to the intervals used to group the data. The second column will be the upper cutoff of the interval. Also include the lower cutoff of the first interval, as shown in the screenshot below. Creating intervals and cutoffs for a histogram Highlight the data, then select Statistics Descriptive Statistics Frequency Tables Histogram. A dialogue box will appear with the input range pre-filled. Click the Cutoffs tab and choose Predetermined cutoffs. Use the selection tool to highlight the cutoffs created earlier. Using predetermined cutoffs

10 The Bins tab provides various options as to how the data should be grouped into intervals. The notation used is standard for describing intervals, but for those unfamiliar with this notation, select the second-last option as shown below. This option places a datum into an interval if it is greater than or equal to the lower cutoff, and strictly less than the upper cutoff. Defining intervals By default, the histogram tool does not produce a graph, and produces a frequency table on a separate sheet. Since a graph will be created manually, click OK to create the table. The result is below. An automatically-generated frequency table Verify that the data has been properly tallied. Once convinced, select all of the data in column C and click Insert Chart. Select a Column chart, and place it on the worksheet. Right-click and select Properties to make some changes.

11 Since a histogram typically represents continuous data, a column graph may not be appropriate. The gaps between bars can be eliminated by selecting the Series and changing the Gap to 0%. Eliminating the gap between bars The default labels on the x-axis do not really make sense. The intervals defined on Sheet1 can be used in place of 1-7. To do this, select Series1 from the list and click on the Data tab. Next to the Labels field, use the tool to select the intervals from Sheet1 of the workbook. The labels on the x-axis should change to those that were created earlier. Labelling intervals As with box-and-whisker plots, it is possible to add a title, label the axes, change colours, and so forth. A completed histogram is shown on the next page.

12 A histogram showing the frequency of player ages A frequency polygon is a line graph. Using the data generated from the Histogram tool, it is possible to make a frequency polygon by selecting Line from the chart options, as shown below. Compare it to the histogram above. A frequency polygon showing the frequency of player ages

13 Both histograms and frequency polygons can display cumulative or relative frequencies if desired. The cumulative frequency polygon below was generated using the formula in column E. A cumulative frequency polygon showing the frequency of player ages Similarly, the relative frequencies in column D were obtained by dividing each frequency in column C by the sum of all of the frequencies. For example, cell D1 contains the formula =C1/sum(C3:C9).

14 Scatter Plots and Regression Analysis Consider the following data relating the length of an object, in centimetres, to its mass, in kilograms. Mass vs. length of an object Select the data in columns A and B as shown, then insert a chart. Select the XY chart, as shown. Creating a scatter plot Place the chart on the worksheet, and right-click and select Properties to access the various options.

15 Select Series1 from the list, and click the Add button. From this submenu, move down to Trend Line. There should be various types of trend lines, including linear, polynomial, and exponential. In this case, select a Linear trend line and you will see Linear Regression appear beneath Series1 in the list, and a line of best fit on the scatter plot preview. Adding a line of best fit to a scatter plot To add the equation of the line of best fit (and the correlation coefficient, R2), click Add again and select Equation. The result should look something like this. Adding the equation of a line of best fit

16 As with any chart, it is possible to label and decorate a scatter plot. A sample is below. A linear regression applied to a scatter plot To perform a different type of regression, select a different trend line from the available options. For example, to perform a quadratic regression instead, select a Polynomial trend line with an Order of 2, as depicted below. Selecting a quadratic regression

17 Compare this curve of best fit to the line of best fit generated earlier. Note that the chart should probably be enlarged and the position of the equation changed so that it does not obscure the graph. A quadratic regression applied to a scatter plot
