    Re: Is this approach permissible?

    All of a sudden, it's just greek to me

    Sorry guys to bother you again. I read in my statistiscs book that I need more than one independent continuous variable to create a regression model.

    I mean, I receive one continuous variable (Index of Social Media) and have one categorial variable. Is this not perfect for a independent t-test?

    I would like to investigate, whether successfully funded initiatives use more social media.
    So "sucessfully funded" is your grouping variable
    and number of channels used is your dependent
    variable. A beginner's choice could be using the
    U-test, then.
    I read in my statistiscs book that I need more than one independent continuous variable to create a regression model.
    You need more than 1 independent variable to create a MULTIPLE
    regression model. For a SIMPLE regression model you just need
    1 IV.

    Well, my statistiscs book suggests a T-test for that...

    Quoting:

    Two variables:
    one categorical, independent variable (e.g.males/females);
    one continuous, dependent variable (e.g. self-esteemscores).

    Am I wrong now?!

    Re: Is this approach permissible?

    The issue is that it makes more sense to think of your social media index as the independent variable and the binary "Funded" as the dependent variable.
    I don't have emotions and sometimes that makes me very sad.

    I do not know how large your samples are and/or whether assumptions
    of the t-test are fulfilled. Did you already check assumptions? U-test is
    a robust alternative if you should encounter problems with the t-test.

    Well, I collected some cf initiatives that fall under the category "music" on Indiegogo. Is this sample random?! I mean a took a sample that is from the overall crowdfunding pool "population"

    I checked the normality assumption and skewness and kurtosis are under 2, which my book says is good

    Thanks
