    Sports data set

    You can't treat the same team as "different" teams because they're correlated and mess up your analyses. You'd need to do some type of longitudinal modelling line time series or mixed-effects models to account for the repeated instances over time.

    Am I posting questions in the wrong place?

    Have you considered posting on cross-validated? https://stats.stackexchange.com/ Sometimes questions that aren't answered here get an answer there!

    Looking For The Formula Used for the Chi Square Table

    Well... you need to use the quantile function or inverse CDF of the chi-square distribution for that and I don't think there are closed-form expressions for it because of the gamma functions involved.

    HLM Simulation

    Let's do this step by step. We'll start with something simple and build towards a full HLM. First, you have a few important-yet-ambiguous statements that need more precise definitions. What does "general characteristics of the attachment", "predicts the burnout risk" and "higher the attachment...

    Some questions to answers

    Perfect. That means my "help" had the intended effect.

    Some questions to answers

    This seems very relevant to these questions Particularly to Question 10.

    Serial & Parallel mediation Hayes Process

    You mean there is no model in the Hayes PROCESS macro that matches yours?

    Factor analysis, determinant < .00001

    Can you post the matrix on here?

    Power analysis for moderated mediation (and a small research design question)

    For models like yours the only way to approximate power is through a computer simulation. This can get you started: https://www.tandfonline.com/doi/abs/10.1207/S15328007SEM0904_8

    Non-linear diagnostics

    What's with the groupings in the "Allowed" plots? Do you have a categorical predictor there?

    Journals statisticians read

    Well, the Harvard Data Science Review is a good place to start: https://hdsr.mitpress.mit.edu/

    Regression model and G*Power

    I'm sorry but what is the question here? What you're reporting seems pretty normal with respect to how power works.

    Simplifying Binomial Coefficients with large numbers, i.e., factorials of large numbers

    You're running into a combinatorial explosion problem, which is very typical of discrete mathematics. But it shouldn't be too difficult to simplify the expression to something you can evaluate. If you're unfamiliar with how to simplify factorial ratios, here's something to get you started:

    What's the probability of getting at least 3 concecutive heads in 10 tosses of a coin?

    This seems useful and relevant to your question

    Is my scatterplot homoscedastic/heteroscedastic?

    Definitely heteroskedastic. Is your dependent variable discrete?
