Are there #data studies and #research on most effective ways to share info about the vaccine? I've been having lots of convos with vaccine hesitant ppl and a common thing is no data culture, so they don't understand the #chart + #statistics . So, what did I do ? 1/
I asked vaccine hesitant ppl questions instead of throwing info at them. Showing up saying "Look at this data!" isn't helpful, or working. We all have different approaches, values, and things that resonate. Do you want to be told you're right, or do you want to be effective? 2/
I started asking vax hesitant ppl questions after our talks, too. What did I say that landed? How did you feel about this fact? When did I say things that frustrated you? What info had you heard before, and what was new? How do most people approach you? How are you irl? 3/

If you are at #RSS2021Conf this morning, check out our invited session on Contagious disease #statistics and #misinterpretation of #COVID dynamics and data with @AdamJKucharski and @AyisSalma
11:40am, Exchange 10
First speaker is @AyisSalma, reflecting on the subtle but important difference of what we think and what data are.
#COVID19 statistics are easily misinterpreted Image
Statistical anomalies in calculations of #COVID19 infections and deaths meant it appeared that no-one ever recovered!
And these figures influenced government #publichealth decisions Image

Does a PhD degree in mathematics or statistics give me an edge over someone with just a bachelor's degree in economics if I want to work in a hedge fund or an investment bank (especially in the current changing field)?
PhD degree can be helpful if you are interested in working as a Quantitative Risk/ Trading Analyst.
I personally feel that Economics and Finance have been hijacked by Physicists, Mathematicians and Statisticians.
There’s too much #Charlatanism in the subject.
Economics is the envy of Physics these days.

Find the median and the quarts parts of a statistic sequence in #pythonprogramming: a thread
1/ First write an median function which find the half indice of a list using n = len(list) (lenght of list) means (n-1)/2 if n is odd and between n/2 - 1 and n/2 if n is even.
In this function, we particularly use % for design arithmetic rest and int operator to convert float to integer. NB: we suppose that at the beginning, list is range by increase order.
2/ Afterwards we define a new function using same logic, but in more take an list of notes,
create a new list knowing that value of first list list[i] design students number who have been the note i. And send the median of the new list.

1/9 Identification of "meaningful change" is a key area when working w patient-reported outcomes. Nevertheless, this seems to be another area of applied #psychometrics / #statistics where rituals may have replaced understanding & deliberate practice.

🧵 w some QLR-promotion😊😅
2/9 w QLR's special issue on "Methodologies & Considerations for Meaningful Change" (under #peerreview) we wanted to initiate a more deliberate approach, now rolled out to any paper submitted aiming to make a methodological contribution to this area👇

#Epistemology #Ontology Image
3/9 An area of concern are discussions around different indices, in particular for classifying intra-individual change: depending on interpretation/ use case, they are all likely not appropriate as they are based on between-indiv variation.

Progress is then not even incremental.

Here's a basic tutorial for how to do simple linear regression in R!

(all in one thread?!)

#regression #Rstats #datascience #tutorial #ecology #Rthread #linearmodel #dataanalysis #statistics

First we are going to load some data. Let's use the built-in "trees" dataset by running:


This dataset is based on 31 black cherry trees trunks: their diameter at breast height (DBH) in inches (girth), height in feet, and wood volume in cubic feet.

Let's first rename the columns for clarity:

names(trees) <- c("DBH_in","height_ft", "volume_ft3")

Asked my students to do stats memes for extra credit and *was not disappointed*.

Guidelines: it had to be original, had to illustrate something they learned in class, and had to use the meme format more or less properly. ImageImageImage

#Coronavirus #STATISTICS

Oxford University has developed an instrument that allows the strictness of corona rules to be compared internationally. A scale from 0 to 100 is formed from various indicators, with 100 representing the strictest rules.
Among other things, school closings, contact restrictions and rules for the world of work are used. The statistics page "Our World in Data" summarizes the most recent values ​​currently available.
This shows that none of Germany's neighboring countries is as strict as we are at the moment.

Germany: 77.78
Denmark: 62.96
Poland: 73.15
Czech Republic: 75.93
Austria: 75.93
Switzerland: 60.19
France: 70.37
Luxembourg: 55.56
Belgium: 60.19

The pandemic has worsened inequality, as the world's richest have made massive gains while the world's poor have fallen further behind, a new Oxfam report called 'The Inequality Report' finds.
During the pandemic, the combined wealth of the world's ten richest men rose by $540 billion. A stock market collapse during the first months of the pandemic saw the ultra-wealthy experience dramatic reductions in their wealth. Nevertheless, that setback was short-lived,
and the fortunes of the top 1,000 billionaires returned to their pre-pandemic highs within nine months. Worldwide, between March 18 and December 31, 2020, the wealth of billionaires increased by $3.9 trillion. Their total wealth is now $11.95 tn,
