This calculator compares observed and expected frequencies within (up to 20) categories using the chi-square test. Enter the names of the categories into the first column, then enter the actual counts observed and expected for each group. ...
Example 2: Data visualization Interpretation We will graph a Chi-square distribution with degree 5 and size 1000, and use Kernel Density Estimation to fit the graph. We can see this is a pretty good fit. To be continue... 作者:乌然娅措 链接:https://www.jianshu.com/p/a352952a7899...
Learn what Chi-square distribution, also known as the X^2 distribution, is. Understand the Chi-square graph and find Chi-square distribution examples.

Looking at the graph above, most people would think that the type of movie and snack purchases are independent. If you perform the Chi-square test of independence using this new data, the test statistic is 0.903. The Chi-square value is still 7.815 because the degrees of freedom are sti...
I don’t completely understand the problem that you are having with the chi-square test, but this is not really a great test for normality. Shapiro-Wilk is usually one of the best tests for normality. I would also create a graph (e.g. Q-Q plot) to mak...
The chi-square test for trend tests whether there is a linear trend between row number and the fraction of subjects in the left column. It only makes sense when the rows are arranged in a natural order (such as by age, dose, or time), and are equally spaced. ...
The president of the dog food company looks at your graph and declares that they should eliminate the Garlic Blast and Minty Munch flavors to focus on Blueberry Delight. “Not so fast!” you tell him. You explain that your observations were a bit different from what you expected, but the...
The graph below displays this result visually. Two-Tailed Tests For a two-tailed chi-square test, divide your significance level in half because the test splits the area between the upper and lower tails. Because chi-square distributions are greater than zero and not symmetrical, its critical ...
