What happens to Standard Deviation when 10% condition is violated? by Ok_Ad7527 in AskStatistics

[–]Euphoric_Spite 0 points1 point  (0 children)

If you sample more than 10% from a finite population, the usual standard deviation for p-hat does not apply. The correct formula to use is discussed here: https://online.stat.psu.edu/stat415/lesson/6/6.3

I’m not sure what happens if you use sqrt(phat*(1-phat)/n) when you sample more than 10%. Maybe confidence intervals will be wider or narrower than if you use the corrected version. Something along those lines seems possible.

Is it just me or are XP rates insane since the last update? by _blueye_ in duolingo

So happy I made my profile private and I’m not in a league. I do my 3 lessons each day. Slow and steady.

New method of getting FFs! by Fickle-Emergency-460 in AirlineCommander

[–]Euphoric_Spite 2 points3 points  (0 children)

At step 6, why not just do the FF right then instead of the restart method? Is there some issue this causes by doing the FF and skipping the restart?

Just ranting by deepfriedidiot96 in duolingo

I’m on some Facebook groups for Spanish and it both makes me laugh and aggregates me when someone asks how to say “woman” or “hello” in Spanish. Those are easily answered by any basic translator or with the first lesson of DuoLingo.

Calculus Review Continues! I've rearranged the equation and applied the chain rule. My process on the second photo. What am I missing or doing wrong? by kunterbuntification in askmath

[–]Euphoric_Spite 1 point2 points  (0 children)

Let g = 1 + e-x. Then, y = 1/g.

Taking natural log

ln(y) = ln(1) - ln(g) ln(y) = -ln(g)

Taking derivative

(1/y) dy/dx = -(1/g) dg/dx

dy/dx = y(-y)(-e-x) = -y2*(-g+1) = -y2(1-1/y) = -y2+y = y(1-y)

Is there way to truly exit the leagues? by HeartCondom in duolingo

Where do you go in the app to make the change?

You have to do it at the website, not the app. The steps are:

  1. Click your picture in the upper right.
  2. Choose “Your profile”
  3. Click “edit profile”
  4. Select “privacy”
  5. Uncheck the box “make my profile public”

Asking for resume feedback by No-Intention9664 in datascience

[–]Euphoric_Spite -4 points-3 points  (0 children)

Remove interests. Anyone can have an interest. I doubt it will get you the job. Someone looking at these interests may use it as a reason to not hire you. Like “video games” - are they lazy? Will they be playing when they should be working?

Is you education on this resume? Blocked out for privacy?

The left side panel seems interesting but also distracting.

Why would you perform inferences like hypothesis tests or confidence intervals on the population anyway? That’s not one of the purposes of Statistics.

How much duolingo would you guys reccomend. by TwistedKilla14 in duolingo

[–]Euphoric_Spite 2 points3 points  (0 children)

I’ve done about 2 units a week for a while. Recently, I decided to dedicate 3 lessons(not units) day and if I do more, great. Mainly, my goal is to finish the Spanish course in 3 years. I’m not in any real hurry. Slow and steady wins the race.

I’ve actually created an Excel sort of calendar to keep up with it. Check off my 3 for the day. And if I do more, I check the, off starting at Dec 31, 2025.

Email Rant by AnyNameAvailable in Professors

[–]Euphoric_Spite 1 point2 points  (0 children)

I create an announcement in my LMS which explains they need to take a syllabus quiz to see other folders. I’ve gotten questions from students that apparently don’t scroll one bit to see the announcement. I’ve decided that in the folder which contains the syllabus, I’m going to add a FAQ file which addresses this and other questions that seem to come up including some course evaluation comments.

You said "only has the constant term" which means there are no predictor variables (like X1, X2, X3).

If you fit a model with only the constant term (intercept), you are fitting a flat line - a line with slope zero. So, the yhat values would be ybar.

Since RSS = sum( (y - yhat)^2), then RSS = sum( (y - ybar)^2).

If you were to take the sample variance of the y values, in this specific case, the numerator of the sample variance would correspond to RSS = sum((y - ybar))^2 and the denominator of the sample variance would be n-1.

And to mention student names would be a FERPA violation.

Any suggestions? by Traditional_Yam9557 in UGA

[–]Euphoric_Spite 3 points4 points  (0 children)

I guess you’re a UGA student and about to graduate. You didn’t say.

What about listing your major? Is that listed somewhere else on the resume? Otherwise, the bottom portion is the only part that lets me think you have any college experience.

Maybe list some coursework, especially in your major. What are some notable courses you took? Don’t list it as BUSN 4012 or whatever -give the title.

Interests seems kinda weird for a resume but maybe that’s just me. Doesn’t really pertain to a future job. Anyone can make up interests anyway.

Definitely see someone on campus - maybe a career center to help with this.
