Statistics > Basic Statistics > Descriptive Statistics Statistics > Basic Statistics > Descriptive Statistics Descriptive Statistics computes descriptive statistics for a set of input column variables or for groups of data within a set of input column variables. It displays the results in the log window and also optionally stores them in Datasheets. To use the utility, use the following steps: Select Statistics > Basic Statistics > Descriptive Statistics to open the utility. In the Input Variable(s) text box, enter the names of the columns. Separate column names by spaces (e.g. c2 c4), and use a dash to indicate a range of columns (e.g. c10-c15). In the By Variable drop-down menu, select the variable that will be used to group data values in each column. Select the descriptive statistics to be computed by checking their corresponding check boxes. Check the Store Results in New Datasheet box if you would like to store the statistics in new Datasheet(s). Statistics for each input variable will be stored in separate Datasheet. Click OK to finish. The results are displayed in the log window and stored in new Datasheet(s) if specified. The following descriptive statistics are available: Mean SE of mean Standard deviation Variance Coefficient of variation First quartile Median Third quartile Interquartile range Mode Percentile Trimmed mean Sum Minimum Maximum Range Sum of squares Skewness Kurtosis MSSD N nonmissing N missing N total Cumulative N Percent Cumulative percent
