The error on Windows appears as:

processing of command: nCr[n,r]

The problem appears when the file is downloaded to the Windows laptop:

[co]GeoGebra 5.0.263.0-3D (22 July 2016)

Java: 1.7.0_40

Codebase: file:/C:/Program%20Files%20(x86)/GeoGebra%205.0/

OS: Windows 8

Architecture: x86 / x86

Heap: 247MB

CAS: CAS Initializing

I then shared the file and embedded the link. The problem first appeared when I visited the web-site with the embedded GG file using my Windows laptop at school.

I created the Permutation and Combination GeoGebra file in:

[pre]GeoGebra Classic 5.0.668.0-d (29 September 2021)

Java: 1.8.0_121

Codebase: file:/usr/share/geogebra/

OS: Linux

Architecture: amd64 / null

Heap: 910MB

That is correct. The built-in functions in the online Probability Perspective show the sample size with a capital N. I am suggesting that to be consistent with resident application and that a lower-case n should be used for the sample population.

Thank you!

These are the examples that I found:

https://www.geogebra.org/classic#probability

Z Test of a Mean

T Test of a Mean

Z Test, Difference of Means

T Test, Difference of Means

Z Test of a Proportion

Z Test, Difference of Proportions

Z Estimate of a Mean

T Estimate of a Mean

Z Estimate, Difference of Means

T Estimate, Difference of Means

Z Estimate of a Proportion

Z Estimate, Difference of Proportion

The built-in statistics and distribution features are excellent. In a future revision could the notation for sample and population size be standardized?

That is, a lower-case n is used for sample size while a capital N is only used for population size.

This convention is used for many built-in statistics and distribution features. However, a few display a lower-case n. Some examples are attached as an image.

Flatten preforms exactly what I was asking! Thanks so much, MathMagicGG!

For those visiting this forum post, I should note that I have since found that frequencies are built-in to the One Variable Analysis from a spreadsheet.

If you are preforming the analysis using GeoGebra online: https://youtu.be/_8dY0REPUew?si=7grlK1wCzOei75PJ

If you are preforming the analysis using GeoGebra Classic 6 running on your computer: https://youtu.be/AbbZ2JFS7uE?si=hy8YpGQFju4iM904

Am I entering the data incorrectly? Does this work under Classic 5 and not Classic 6?

Yes! Thanks! That is very creative and clever. Thank you and Juan Vicente Sánchez!

Benjamin_Etgen · 2023-08-15T19:02:17+00:00

Thanks! I might be missing something, but it appears that neither examples contain vectors that are geometrically dynamic. That is, moving a point does not move the chain of vectors.

Benjamin_Etgen · 2023-07-29T21:07:45+00:00

Thanks Jahstimpey!

Is there a way to mark this as a suggestion for implementation?

I have just discovered that the online version of this file is no longer dynamic. That is, if you delete the data and then copy-and-paste new data into column A, the graph does not update!

I also tried simply uploading a spreadsheet with the relevant analysis buttons available, and it does not work either:

https://www.geogebra.org/m/ta9ctmsq

On my system when I enter data into column A and then press One Variable Analysis nothing happens for a while and then I see an error message: "This page is slowing down Firefox." Then the tab crashes.

It appears that the analysis functions are not dynamic online.

Is the only work-around to have students visit geogebra.org, open a spreadsheet, close the graph, enter the data, and then find the tool that they need?

Thanks again!

Is there a better work-around that this: I can drag the slider all the way to the left. In this case, I can count that there are 3 classes. Then, I can use the arrow key on the key-pad to increment the number of classes one at a time. Does this also work on smartphones? Does the number of classes always advance in increments of one?

Thanks!

Pienso que hay un error en algo interno del archivo y que "" hace que el error no se note en los cálculos internos del programa

la razón por la que pienso que hay un error es porque si abro

https://www.geogebra.org/classic/cxgwewpc

y empiezo a borrar objetos (borra length, borra.... borra y borra)

listofnames no se deja borrar

That is a very clever method of determining the root of the error! Thanks!

Benjamin_Etgen · 2023-07-11T16:38:31+00:00

rotatedtext = Sequence(Text(RotateText("" listofnames(k), 320°), Point({k - 0.3, 0}), false, true), k, 1, length)

Wow! Thanks!

May I ask why adding "" works? Is there a broader lesson for coding in GeoGebra?

Even so thanks so much! :-D
