1 The introduction to SPSS Ⅱ.Tables and Graphs for one variable ---Descriptive Statistics & Graphs

2 Frequencies A good place to start looking at your data.

3 Frequencies  Select one or more categorical or quantitative variables.

4 Frequencies  Click Statistics for descriptive statistics for quantitative variables.

5 Frequencies  Click Charts for Bar charts, Pie charts, and Histograms. Also, you can create all the following charts in Graph. Quantitative variables Categorical variables

6 Frequencies  The display style.

7 Descriptives

8 Descriptives command provides the sample size, mean, std. deviation, minimum, maximum. If you were interested in another summary statistic, you could click on the Options button, and find several other available statistics.

9 Graphs

10 Graphs---Simple Bar chart  Creates a chart summarizing categories of a single variable. Bar height represent a function of either the category variable itself, or another summary variable.  Creates a chart summarizing two or more variables. There is one bar for each variable.  Creates a chart summarizing a single variable by individual cases. One categorical variable Two categorical variables

11 Graphs---Simple Bar chart Numeric or String variable How the data are represented on the scale axis. Categorical variable

12 Graphs---Simple Bar chart

13 Categorical variable

14 Graphs---Simple Bar chart Bar represent -other statistic

15 Graphs---Simple Bar chart

16 A paneled chart is a grid of subcharts. The subcharts are of the same chart type and share axes, but for a different group of one or more categorical variables.

17 Graphs---Cluster Bar chart Categorical variables Select a cluster variable used to group bars.

18 Graphs---Cluster Bar chart

19 Graphs--- Simple & Cluster Bar chart

20 Graphs---Stack Bar chart

21 Each stack consists of a bar divided into segments stacked on top of one another.

22 Graphs---Simple & Cluster Bar chart

23 Graphs---Interactive---Bar chart Using the different colors or styles to distinguish each category.

24 Graphs---Interactive---Bar chart

25 Graphs---Pie chart

26

27 Graphs---Interactive---Simple Pie chart

28

30 Graphs---Interactive---Clustered Pie chart

31 Graphs---Histogram A histogram groups the values of a variable into evenly spaced groups (intervals or bins) and plots a count of the number of cases in each group. The count can be expressed as a percentage.

32 Graphs---Interactive---Histogram

33

34 You can modify the min and max values shown on a histogram, as well as the interval width. This is particularly useful when outliers cause the majority of values to cluster in a few bars.

35 Graphs---Interactive---Histogram

36 Graphs---Boxplot Boxplots show the median, interquartile range, outliers, and extreme cases of individual variables.

37 Graphs--- Boxplot---groups of cases label outliers or extreme cases on the plot, otherwise, case number

38 Graphs--- Boxplot---groups of cases

39 Number of years using the Internet

40 Graphs---Boxplot---separate variable

41

42

43 Graphs---Interactive---Boxplot

44

45 Edit Chart The Chart Editor provides a powerful, easy-to-use environment where you can customize your charts and explore your data. Double click anywhere on your chart.  The Edit Chart Window displayed.  There are several buttons displayed across the top and down the left side of the interactive graph.

46 Edit Chart

47  Select a chart element, and then from the menus choose: Edit Properties Collapse small parts.

48 Edit Interactive Chart
