Redesign Styling Update #2: Updated Data Sources!

Hi all, ​ In the redesign theming, we’ve now got two sets of data sources in the menu bar up top. I’d love for additional suggestions of repositories to include, as well! If we get enough, then consolidating everything into a maintainable wiki page here on /r/statistics might be the move. ​ As always, please reply with questions, concerns, or suggestions. ​ –Toasty submitted by /u/mmm_toasty [link] [comments]

Why do people always assume math majors want to become teachers?

Whenever someone hears that I am majoring in math, I always get the response “ what are you going to do with your degree?” Or “so you want to be a teacher”. I believe that math is applicable to almost anything but I’m always met with these responses. Does anyone else get annoyed by this? submitted by /u/stressedout4 [link] [comments]

How do you structure your work?

Hi everyone, I recently started an internship in Talent Innovation and Diversity and Inclusion as a data scientist. My background is in psychology, with a masters in statistics and psychometrics. My first big report was due today and what I noticed is that my work flow needs to be structured in a different way. The way we were taught to start projects, is to explore the data and play around with it to get a good understanding of the data itself before trying to answer the assignment or question. Up until now, I never really structured this “playing around”, meaning: I never systematically reported my findings in this stage nor did I have a ‘list’ of things that I certainly wanted to look at. Writing this report, I realised that a more systematic approach will save me a lot of time, and will also create a “standard” for my work. As I am the first one with a statistical background in this department, and because I want to develop a solid statistical working style, I am very curious to hear how you do it. How do you structure your work/reporting/analyses? Do you have a system or strategy? Or maybe a vision on how work flow should be? Any links to further documentation, discussions or other posts are also highly appreciated. It’s a broad question, but I’m open to hearing very different experiences or opinions, it doesn’t require a one size fits all answer and I’m also not looking for a magical solution. Looking forward to reading your responses! submitted by /u/leendersh [link] [comments]

Analyzing disruption/moderating third variables with ordinal scales…

Hi everyone, my knowledge of statistics limits itself to what I learned at university studying media and communication science (the basics of everything, or so I thought). My gf is currently writing her thesis and ended up with less-than-ideal data: All of her scales are basically ordinal (including a few Likert-scaled questions). Her H1 had to be analyzed via Spearman’s rank correlation because of the ordinal scaling and ended up being r(s) = .137, p = .282 (at alpha = 95%). That’s fine per se, but now the H2 and H3 are supposed to test the same relationship between IV and DV but each with a moderating/disrupting variable introduced (different variable for H2 and H3, same IV and DV though). For metric DVs I’d just try to calculate a multifactorial ANOVA, but with ordinally scaled variables, how do we do that? I seem to be stuck. Thank you in advance for your help! submitted by /u/strikedamic [link] [comments]

Looking for advice on how to model some data.

We have observations of individuals at various points in their life. We are curious if Variable A predicts later values of Variable B (i.e., if being high on A early on means you will be high on B later on). The trick is that everyone was observed at different time points. Here is some example data to help imagine what I mean. Person Age A B 1 12 2 4 1 15 3 7 1 17 4 8 2 14 1 2 2 20 1 8 I know it will require a mixed effects model. But I’m unsure how to model the relationship between A and B. My initial thought was to have each value of A predict the next observation of B. The problem is that there are different amounts of time passing between each observation for each person. Another thought would be to dichotomize the data. Perhaps take the median age across all individuals and then compute the averages of A and B for each person below and above that value. Any advice? submitted by /u/UnderwaterDialect [link] [comments]

Simple Questions – July 12, 2019

This recurring thread will be for questions that might not warrant their own thread. We would like to see more conceptual-based questions posted in this thread, rather than “what is the answer to this problem?”. For example, here are some kinds of questions that we’d like to see in this thread: Can someone explain the concept of maпifolds to me? What are the applications of Represeпtation Theory? What’s a good starter book for Numerical Aпalysis? What can I do to prepare for college/grad school/getting a job? Including a brief description of your mathematical background and the context for your question can help others give you an appropriate answer. For example consider which subject your question is related to, or the things you already know or have tried. submitted by /u/AutoModerator [link] [comments]

Weekly /r/Statistics Discussion – What problems, research, or projects have you been working on? – June 26, 2019

Please use this thread to discuss whatever problems, projects, or research you have been working on lately. The purpose of this sticky is to help community members gain perspective and exposure to different domains and facets of Statistics that others are interested in. Hopefully, both seasoned veterans and newcomers will be able to walk away from these discussions satisfied, and intrigued to learn more. It’s difficult to lay ground rules around a discussion like this, so I ask you all to remember Reddit’s sitewide rules and the rules of our community. We are an inclusive community and will not tolerate derogatory comments towards other user’s sex, race, gender, politics, character, etc. Keep it professional. Downvote posts that contribute nothing or detract from the conversation. Do not downvote on the mere fact you disagree with the person. Use the report button liberally if you feel it needs moderator attention. Homework questions are (generally) not appropriate! That being said, I think at this point we can often discern between someone genuinely curious and making efforts to understand an exercise problem and a lazy student. We don’t want this thread filling up with a ton of homework questions, so please exhaust other avenues before posting here. I would suggest looking to /r/homeworkhelp, /r/AskStatistics, or CrossValidated first before posting here. Surveys and shameless self-promotion are not allowed! Consider this your only warning. Violating this rule may result in temporary or permanent ban. I look forward to reading and participating in these discussions and building a more active community! Please feel free to message me if you have any feedback, concerns, or complaints. Regards, /u/keepitsalty submitted by /u/AutoModerator [link] [comments]
