WebThe chi-square distribution is equivalent to the gamma distribution where α = k/2 and β = 2. Chart. Figure 1 displays the graphs of the pdf with degrees of freedom df = 5 and 10. As df grows larger the fat part of the curve … Web3.247. 3.940. 4.865. 15.99. 18.31. 20.48. 23.21. The table tells us that the probability that a chi-square random variable with 10 degrees of freedom is less than 15.99 is 0.90. Therefore, the probability that a chi-square random variable with 10 degrees of freedom is greater than 15.99 is 1−0.90, or 0.10.

WebMay 20, 2024 · Revised on November 28, 2024. A chi-square (Χ2) distribution is a continuous probability distribution that is used in many hypothesis tests. The shape of a chi-square distribution is determined by the parameter k. The graph below shows examples of chi-square distributions with different values of k. WebA mosaic plot is a special type of stacked bar chart. For two variables, the width of the columns is proportional to the number of observations in each level of the variable plotted on the horizontal axis. The vertical length of the bars is proportional to the number of observations in the second variable within each level of the first variable.
