Hey everyone! We're back to #SundayStats! We're working from Navarro's learningstatisticswithr.com and this is only our second week, so it's easy to catch up if you want to join in!
Here is where we started last week: bsky.app/profile/exce...

2.5 - Experimental and non-experimental research
"When we make this distinction, what we’re really talking about is the degree of control that the researcher exercises over the people and events in the study," Navarro says. #SundayStats

Section 2.6 - Assessing the validity of a study
You remember we talked previously about precision vs accuracy (which may be more familiar terms).
Validity is accuracy. How close is your data to right and true (rather than to repeated measures of itself)? #SundayStats

Jedenfalls, gestern war erst der zweite Sonntag, alles Bisherige findet ihr unter #SundayStats und ich bin definitiv Fan
(PS: ich habe auch gerade ein Paper mit einer Statistikerin zusammen geschrieben und es war ne besondere Erfahrung 😂 Stay tuned!)

2.4 The “role” of variables: predictors and outcomes
This, too, may remind you of your middle-school science education: independent vs dependent variables. Just because it's older doesn't mean it can't be confused.
When I taught middle school science, we spent a lot of time on this. #SundayStats

2.5.1 Experimental research
"The... researcher controls all aspects of the study, especially what participants experience during the study. In particular, the researcher manipulates or varies the predictor variables (IVs), and then allows the outcome variable (DV) to vary naturally." #SundayStats

2.3: Assessing the Reliability of a Measurement. We're now thinking about the *quality* of a measure: how do we know it's any good?
We'll judge using two constructs: reliability and validity.

(It's important to note that a lot of observational studies-- a lot of what you see in studies based on people's electronic health record (EHR) data, for example-- is simply going to have to take confounds into account. I'm sure we'll get there.) #SundayStats

Honestly as we just discussed in #SundayStats, these are all categorical variables so I'm really done with them after this much math :)

Reliability = precision
Validity = accuracy
Reliability/precision is asking, "if I take a measurement multiple times, what is the likelihood it will be the same?" Your bathroom scale is going to be reliable / precise: if you step on and off again, it should tell you the same thing. #SundayStats

By a similar token, it's possible to have data that is not particularly reliable, but still valid.
(For example, let's say you as a patient have a really fluctuating RDW on your bloodwork but it trends high-ish. Your RDW is still high, even though the measures are not *precise*.) #SundayStats

I was pleasantly surprised how much I liked Slide in real person! It was a lot of fun with a group of friends.
The best part of the week… my work semester for teaching is done, so that leaves so much extra time in mental capacity for games.

Not too bad of a week! Definitely got some fun games in with the family and solo.
Two of these have reviews coming up this week! Are there any you’d like to hear more about?
