    Lightbulb Some questions about SPSS

    I am learning about SPSS, and I have some questions:

    1/ In Chi-square tests, there are terms "Pearson Chi-Square", "Likelihood Ratio", "Linear-by-Linear Association" and "N of Valid Cases". Could you please tell me what do they represent? Moreover, why the Value of Pearson Chi-Square is 6.000a, what does this mean?

    For example
    Chi-square tests
    Value df Asymp. Sig. (2-sided)
    Pearson Chi-Square 6.000a 2 .050
    Likelihood Ratio 8.318 2 .016
    Linear-by-Linear Association 5.170 1 .023
    N of Valid Cases 10

    a.6 cells (100%) have expected count less than 5. The minimum expected count is 1.50.

    2/ In this case, the significance level is .05, so how to define the difference between the expected and actual counts?
    3/ In ANOVA and Post-Hoc Tests, what do "Sum of Square", "Degree of Freedom", "Mean Square" and "subset for alpha" represent?

    Thank you so much!

    Re: Some questions about SPSS

    You do not need to be worried, these are not SPSS-specific concepts
    but statistical concepts. So the information you can get by reading
    introductory books and websites about Chi square statistics and
    ANOVA statistics also applies here.

    Kind regards
