Contingency tables, grouped pie charts, and grouped bar charts display the test using two categorical variables, see the chi-squared test of independence. Frequency tables, pie charts, and bar charts can be used to display the distribution of of a single categorical variable, see the chi-squared goodness-of -fit test.

Buy Chi Square Pie Charts and Me on Amazon.com FREE SHIPPING on qualified orders The degrees of freedom in a test of independence are equal to (number of rows)−1 × (number of columns)−1. Thus for a 2×2 table, there are (2−1)× (2−1)=1 degree of freedom; for a 4×3 table, there are (4−1)× (3−1)=6 degrees of freedom. For chi-square=2.04 with 1 degree of freedom, the P value is 0.15, This bar chart indicates that the largest contribution to the chi-square statistic is in the Medium category. Chart of observed and expected values Use a bar chart that plots the observed and expected values for each category to determine whether there is a difference in a particular category.
To find probability, for given degrees of freedom, read across the below row until you find the next smallest number. Then move to the top and find the probability. For example, if your df is 7 and chi-square is 21.01, then your probability will be written as P<0.005. Table: Chi-Square Probabilities. The areas given across the top are the areas to the right of the critical value. To look up an area on the left, subtract it from one, and then look it up (ie: 0.05 on the left is 0.95 on the right) What is a Pie Chart? A Pie Chart is a type of graph that displays data in a circular graph. The pieces of the graph are proportional to the fraction of the whole in each category. In other words, each slice of the pie is relative to the size of that category in the group as a whole. The entire “pie” represents 100 percent of a whole, while the pie “slices” represent portions of the whole.
