13:18:30 From Anna S : I can be the host, yes maybe 4-5? We should maybe also tell them to talk with each other in those groups and discuss the answers? 13:18:41 From Anna S : Sorry ;( 13:30:33 From Kasper Hede Nielsen : Should expect uniform distribution of the numbers 13:30:48 From Marta Mrozowska : I noticed when I was typing in the numbers, I typically typed 1-5 together and 6-0 together 13:31:08 From Marta Mrozowska : because of how my keyboard is set up 13:31:43 From Jaime Caballer Revenga : maybe operating with another true random number (irrational, e.g. pi, e), and see if the output shows a non-random pattern? 13:32:04 From Liam : fourier transform 13:32:06 From Laurits Høgel : You can check every 2 digit sequence 13:32:06 From Kasper Hede Nielsen : For enough data you should expect runs longer than 1 13:32:22 From Kasper Hede Nielsen : of each digit 13:32:46 From Laurits Høgel : not second digit, but 2-digit-sequence 13:32:47 From Emily Claire Winther Sørensen : check patterns to check if distribution of most probable next digit is also uniform 13:33:08 From Kasper Hede Nielsen : 1/10 ? 13:33:48 From Anna S : Isn't 3 in a row 1/1000? 13:34:25 From Aske Luja Lehmann Rosted : feed all the different random digit sets to an ML algorithm that tries to predict the next number and see if it has any luck with any of them? 13:36:55 From Troels Christian Petersen To Amalie Paulsen(privately) : Ikke i en gruppe?!? 13:37:21 From Troels Christian Petersen : I’ll be back in a minute... 13:37:33 From Amalie Paulsen To Troels Christian Petersen(privately) : Jeg kunne ikke lige logge på zoom, så jeg ved ikke lige hvad vi laver, men har vi regnetime nu? 13:39:11 From Troels Christian Petersen To Amalie Paulsen(privately) : Nej… stadig forelæsning… til 14::00-15 13:40:25 From Efthymios Siamos : maybe compare the likelihood of the numbers ? 13:40:56 From Hjalte : we talked about summing up numbers and seeing if they would be gaussian distributed 13:42:00 From Katriona Mai Landau Gould : Sum all of the numbers in each column, if the numbers are randomly distributed the sums should give a uniform distribution, otherwise it may reveal certain orders people use e.g. switching between sides of the keyboard or moving around parts of the keyboard 13:42:06 From lucaalessi : Shift the numbers in the sequence by 1 step and plot the shifted number sequence vs the original one 13:42:35 From Marcus Nørgaard Weng : Very simple, but might catch something: Compare the averages of all the integers. For so many numbers, the averages should be very close to np.avg(range(10)) 13:42:52 From David : making a histogram of all tripplets (or larger groups) of numbers should look like the histogram of a uniformly distribution. If there are repeating sequences the histogram will be uneven, no? 13:43:26 From Lasse Bonn : is there an approach where we consider the entropy/information of the data 13:44:20 From Marta Mrozowska : Troels, Iminuit was updated 13 h ago and the new version makes your scripts not work; for erda users, install iminuit==1.5.4, then the scripts still work 13:46:50 From Norman Pedersen : would it be unreasonable to filter out the drunk data ? 13:49:45 From Marcus Nørgaard Weng : Do you think there is a correlation between "good"/precise measurements and low self-proclaimed uncertainties. Do people know when they made a precise measurement? 13:50:55 From Marcus Nørgaard Weng : I was thinking about the situation where you've measured the table with the ruler and have to guesstimate your own uncertainty 13:53:51 From Norman Pedersen : what if one has a data set of such size that manual inspection is not possible ? 13:54:01 From jmlin : how to choose 3/4 sigma to reject data? is there any criteria or experience? 13:54:53 From David John Willumsen : Does Chauvenet's criterion have to be applied to one point at a time, or can multiple points be compared to the same 1/2N? 13:55:06 From Peter Andresen : This discarding of data assumes that it follows a normal distribution, but in reality that is not for sure right? So you are trimming the data to look like the distribution you expect? 13:59:33 From David : about slide 15: could you repeat why there is no RMS value in this condition? 14:00:30 From David : thanks 14:07:07 From Peter Andresen : This discarding of data assumes that it follows a normal distribution, but in reality that is not for sure right? So you are trimming the data to look like the distribution you expect? 14:07:59 From Peter Andresen : sounds good, thanks 14:08:15 From Efthymios Siamos : so how can you be objective when peer reviewing others work ? 14:08:47 From Efthymios Siamos : I mean in the statistics as it seems each person does different statistic analysis
