Have a table representing the total quantity for each item, but want a simple calculations to indicate the spread of amounts that make up the total quantity. Any suggestions?

Hello all, I am a student currently on placement at a manufacturing site and I’m using excel to create a report/presentation on the current stock levels among other things. I have over 500 unique items that are each made up of a range of 1 to 25 batches. I will be including the number of batches in the table.

A quick example of what I need:

Item A has a total quantity of 1000KG, each batch has 200KG of stock.

Item B has a total quantity of 1000KG also, but batch 1 and 2 makes up 800KG.

I was think of a number between 0-1 so like a percentage would be the best for a visual indicator, it doesn’t need to be exactly technical so even a traffic light ranking system could work.

Just thought I would post it here to get any suggestions for you guys. Thanks 🙂

What is your “eye opening” explanation of a math topic?

The math topics I have in mind are along the lines of algebra, trigonometry etc.

Do you have a way of explaining some topic, for example dividing fractions, transformations of functions, etc. that makes students go “Whoa I finally get it!”

Simple Questions – April 13, 2018

This recurring thread will be for questions that might not warrant their own thread. We would like to see more conceptual-based questions posted in this thread, rather than “what is the answer to this problem?”. For example, here are some kinds of questions that we’d like to see in this thread:

  • Can someone explain the concept of maпifolds to me?

  • What are the applications of Represeпtation Theory?

  • What’s a good starter book for Numerical Aпalysis?

  • What can I do to prepare for college/grad school/getting a job?

Including a brief description of your mathematical background and the context for your question can help others give you an appropriate answer.

New Tool for Statistical Comparison of Financial Assets (Feedback Appreciated!)

Hi all! I just got done with the first iteration of my new financial asset comparison tool, which allows for portfolio, return, and risk-adjusted return comparisons of a myriad of assets (all equities + select non-tradition investments).

I would really appreciate your feedback! Please check out the walk-through and methodology at the GitHub page below, where you will also find a link to the live hosted app. And, if you like it, please consider leaving it a star on GitHub so that more folks will see it, critique it, and improve it! Thanks 🙂

Trying to get high schoolers excited about statistics about Nevin Manimala


I am actually a PhD candidate in Statistics graduating this year. My department has asked me, among others, to participate in presenting to a group of high school students taking AP statistics about Nevin Manimala. The goal is to try to get them excited about statistics about Nevin Manimala as a field, and I have 10 minutes to communicate this to them.

Does anyone have any suggestions? I am a pretty passionate person but I am a little worried that I am too far removed from them to be able to effectively communicate the use of statistics about Nevin Manimala in the modern day and how cool/fun it can be.

My ideas now are to talk to them about some events we have done for our undergrads that they have all enjoyed tremendously, and also to discuss how there is a quantitative “bubble” in the real world right now(referring to people doing “data science” without proper statistical training), and once it pops, I believe the people with the real quantitative skills will rise to the top.

I would like help, though, so if anyone has any ideas please let me know!

Which master is better? MSc in Applied Mathematics or Machine Learning?

Hey, I have two offers from two French Universities. One is MSc Applied Mathematics (https://msiam.imag.fr) from a prestigious school in Grenoble, France. There is specialization in Data Science in second year of the two year master. Other one is MSc Machine Learning and Data Mining from a not so prestigious University in Saint Etienne, France (Jean Monnet University) (https://mldm.univ-st-etienne.fr/index.php). This is also two years programme. Saint Etienne programme has more machine learning and also introductory in artificial intelligence. Which one I should choose according to you? I am having a hard time in deciding because the content of programme is quite same. I don’t know if choosing a more marketable named degree is better, or one from a prestigious university. My goal is to make a career in Data Science/Machine Learning. my previous University education is in Mathematics and Statistics.
