Can you clarify your use of the term "interaction?" I'm sharing this video with some students and when we talk about interactions in any kind of ANOVA context...we are talking about the unique effects of different categories of multiple IVs on the DV. Here you are just comparing different levels of 1 IV to other levels of the same IV.
Hi Kristie, so good to hear from and even better that you are sharing the content with your students. That is great! Regarding your question, indeed I tend to use the term "interaction" or "contrast" when testing for variations of IV(s) on DV(s). So regardless of the number of IVs. For some reason it works for me when teaching or supervising my students. Hope that helps and wish you a great day!
How do we know if a value is significant? It seems like every time you mention a value is significant it is a number that resembles a .0__ value. Are we comparing this to the .05 significance level? (i.e. the closer the value is to .05, the stronger the significance?)
please dont ask how i am doing in a statistics tutorial. i am a quivering desperate mess. JUST GET IT OVER WITH! ;D
Hey Yara, don't be so hard on yourself. I am sure you will do just fine. Do you best, put some nice music on, a nie drink and enjoy the process. Statistics can be really fun! All the best :)
@@liveinnovationorg thank you, that's really kind. Made my day:)
How to determine bonferroni correction alpha level? is it based on number of dependent variables? or number of dependent variables x number factors of each dependent variable?
hello, I am trying to do this but when I finish it says: Warnings
The large number of columns in the design matrix will cause integer overflow. The large number of columns may be due to too many levels in one or more factors, or to higher-order interactions among factors with many levels. It may also be due to too many factors.
Execution of this command stops.
what can I do?
Hi Aphro! Well, my guess would be that the issue is either your are inputting way too many variables or the set up of the variable/data sheets are causing the issue. So my guess would be to either reduce the number of variables which are being analysed per time, or/and check your variable sheet. All the best!
Same question!!
And I was wondering if you mean that to reduce variables as to reduce the columns instead of the variable size, right?
And also the issue of the data sheet, what’s that mean?
Sorry for asking these pile of questions, as a intermediate user, would like someone like you can lend a hand!!!! And thanks for your time!!!
Thank you very much for the explanation!
I have a question, what tests should I do to measure the influence of a set of variables on the occurrence of a phenomenon in the absence and / or combination of them? I'm working on my thesis and I'm trying to find patterns in the interaction of this variables.
I would really appreciate your help
Hi Sarita, good to hear from you! Well, it is impossible to answer your question. It depends on numerous factors, such as how the questions were structured, how the data was collected, your research objectives and more. My main suggestion is for you to contact your supervisor, who should be more into your research project, to provide you with guidance. All the absolute best!
@@liveinnovationorg I understand. But could you please give some advice so I can read about? I'm currently without supervisor because I haven't
been assigned one yet.
@@saritamariaabarzacancino2189 I am, really sorry, but I do not want to give you an incorrect information, you know? Again, the tests you should apply depends on how they were measured, how the questions were structured and, importantly, what your research objectives are. So perhaps the best would be for you to find a supervisor and discuss with him/her in detail. Only going through it you will know exactly what to do, ok? But I really wish you all the best!
Hello, may I ask if the control variables are also counted as covariates?
Thanks!!
Hi Ann! Depends what you mean by "control variables". If you mean as "control group" variables, then no. They should be compared with other groups. If you refer as variables you will use to control for unwanted variance, then yes, they are covariates. Hope that helps!
