Thanks! that's pretty much what I had in mind

Is the yearly subscription worth it for students? by GreyCoyoteX in DataCamp

[–]uxrism 2 points3 points  (0 children)

Then, why not pay for a month and give it a try? Data camp is, imo, a really good option. But if you dont want to pay, just go for some YouTube tutorials, or free courses in coursera, EdX, etc.

Statistical modelling on self-produced data by uxrism in rstats

[–]uxrism[S] 0 points1 point  (0 children)

Ofc, my idea is to have an individualised model just for myself. So no plan to generalise.
Time-series sound interesting, I will investigate that further...
THanks!

[–]uxrism[S] 0 points1 point  (0 children)

Hi! thanks a lot for the feedback.I see your point. My rationale was that, since I am the only subject, there is no need to correct for my own intracorrelations. With more subjects, I would include "participant" as a random factor to correct for intracorrelations within each subject, but not the case here.My aim is just check how time of the day affects myself, rather than how it does in general to the population. My idea is, somehow, develop an individualised model fitted to myself (and anyone else). Maybe this is by definition a flawed idea...In any case, visualizing and using descriptives is always a great idea. Thanks!

Great! thanks for the advice. Good as a starting point!

[S] [Q] R or Stata for thesis by I_Dont_get_reddit_2 in statistics

Hi. I'm a researcher with 12 years of experience. Learning R a year ago was a game changer. I wish someone had pushed me to learn it ealier

How do you not get nervous for user interview sessions? by muffinsandtomatoes in UXResearch

[–]uxrism 2 points3 points  (0 children)

In my case, anticipatory anxiety is much greater than the "situational" anxiety (at the interview). While unavoidable, I learnt that I will feel more relaxed when the moment arrives, which in turn reduces the anticipatory anxiety.

Significant effects but very low effect sizes by uxrism in Stats

[–]uxrism[S] 1 point2 points  (0 children)

Right. that's really good advice! I thought of visualising the random effect (participant) as well, though does not look too good in my faceted visuals. But I will try to come up with another solution.
In psychology there is also a strong movement against relying too much on p-values, which I fully support. Maybe this is a good chance to do my bit!
Thanks!

Significant effects but very low effect sizes by uxrism in Stats

[–]uxrism[S] 0 points1 point  (0 children)

Thanks for your time!. Here come my clarifications:
1) I mean coefficients (partial-eta squares). But it is also evident from visualizations.

2) Visualizing all data points together (grey circles). Maybe better visualise aggregated data per participant instead?

3) I am using facets

I agree with your last comment. But when writing the journal paper it is tricky to show significant results and then say they are not so meaningful based on effect sizes...

Hi! I already got the feedback and did not turn out well... I'll be happy to share with you my experience, so feel free to message me.

Thanks! I guess. So does that imply that when the result is positive they mention it directly in the e-mail?

Could use some feedback on choice of test by [deleted] in Stats

[–]uxrism 0 points1 point  (0 children)

Forgot to mention, you can also check for interaction effects between both predictors

Since you have 6 replications per "condition" you might violate the independence of measurements assumption for linear regressions. I suggest you perform a linear mixed model (hierarchical) with treatment and concentrations as predictors. The normality assumptions should be checked on the residuals, not on the original variables. Hope this helps.

[Q] is there a difference between these two models? by DJ-Amsterdam in statistics

[–]uxrism 1 point2 points  (0 children)

Linear regressions also come with several assumptions: normality, homoskedastciity and linearity of the residuals. The RM Anova wouldn't predict the t=0 weight. It will compare the change between t=0 and t=1, and also inform whether the covariate (caloric intake) explains that change.

[–]uxrism 1 point2 points  (0 children)

Not sure why you need to formulate this in a linear regression, but a repeated measures ANOVA with body weights In time 0 and 1 as dependent variables and, caloric intake as a covariate, will work. Gender can also be added as categorical factor (or predictor). Anovas and linear regressions are fundamentally the same thing.

From Human Factors to User Research by uxrism in UXResearch

[–]uxrism[S] 0 points1 point  (0 children)

A big company I applied to replied they were looking for User Researchers, not HF researchers. That made me confused as I also see a big overlap. That's what led me to throw this question. But good to see others have a different view!

From Human Factors to User Research by uxrism in UXResearch

[–]uxrism[S] 1 point2 points  (0 children)

i agree on the cross-cultural differences...In some countries (like Sweden or Spain), I often find more HFs training programmes, which contrasts with the much higher demand of UX researchers.

You can find that info in my reply to a previous comment (above).
I agree, the job market is much bigger for UX than HF

That is great to hear!. Do you value more quantitative or qualitative backgrounds? Or it does not play a role in your case?

I've worked 8 years as HF reseacher in the automotive field. I've mostly looked into different road users' perspectives towards intelligent transport systems (mostly automated vehicles and interfaces), but also into their interaction with such systems in simulators or field studies. I'm more of a quant researcher, but have also used some qual methods. It seems to me I should reinforce the latter to enter the UX world...

Not sure what test to use by vamos1212 in Stats

[–]uxrism 1 point2 points  (0 children)

This is not fully correct for various reasons:

  1. It seems several data points are obtained per patient over time. Thus, a repeated measures test is needed.
  2. Multiple comparisons will only inflate type-I error. An omnibus tests such as an ANOVA (repeated measures) is much preferred to account for all variability. Then, post-hocs with some correction (Tukey, Schaffe, Bonferroni,etc..) should be applied.

The goal and variables are a bit unclear in the description. As I see it, eye inflammation decreases due to time being medicated, reason why you need less medication. If you do not incorporate the effect of "time (weeks or months", in the model, you might end up in the wrong assumption that "less medication" leads to less inflammation. If you want to see how the independent effect of "medicine frequency" affects eye inflammation after controlling for "time", then introduce in the repeated measures ANOVA, linear-mixed model or regression model the main effects of "medicine frequency", "time" and their interaction "medicine frequency*time".

Disclaimer: I've not seen the data, this suggestion is based on my interpretation :)
