    I appreciate how organic this video is. Hearing you talk about ideas that you come across gives us a picture of what kind of questions we should be asking ourselves. You also addressed being cautious with the analysis i.e. the "elevator pitch".

    This is really great content. I love that you went through the entire process. Your on-the-fly thinking is really amazing. I would love your insight about going into in-depth analysis when the request is for a simple quarterly summary. This type of in-depth analysis might take you an hour or less, but it would take me half a day. What is the benefit of dedicating so much time to an exploration that wasn't requested? I imagine when you deliver the original request, then a follow-up request might come for an explanation. I have never worked in industry so I am just curious how this all works.

    • @mattbrattin
      @mattbrattin  3 года назад +9

      Very important question, and an insightful one as well.
      My reaction is, as it is to most things, it depends.
      It depends on the timing you were given, the urgency of the request, and your comfort level with the stakeholder that you can anticipate their questions.
      As a baseline, it is completely acceptable to "do what was asked". Full stop. But, you will get questions, because that's the name of the game.
      Over time, if you have ambitions to move up, you need to show initiative and understanding beyond the surface level and start to go through this exercise where you're 2,3,5 steps ahead and can have this pretend dialogue with the stakeholder and anticipate questions. It may take you half a day at the start, but eventually it'll just be part of the process and you'll get faster and more precise.
      Don't let your current experience dictate, or worse, limit your push to get better.
      Hope that made sense!

    Great, Matt! The format of watching you work and think as you go was very helpful. Also appreciate you calling out your keystrokes - I learned some cool new stuff!
    I did get lost at one point though, at about 27:09 timestamp. I don't understand the formula for cell O41. I thought to forecast Q2 2021 sales, it would be the Q2 2020 sales plus 4% which I thought would be C41*(1+J41). Please explain again why it's C41/(1-J41).

    • @mattbrattin
      @mattbrattin  3 года назад +4

      Good question, and the answer is it's not! I don't know why I did that to be honest. Mathematically it works out almost the same and a lot of times I'll see people use these formulas interchangeably, but there are slight differences.
      Base *(1+growth rate) is correct and I actually use that in the 4th video.
      Base/(1- growth rate) implies the base is, in this case, 96% of the forecast value and forecast is 100%, not actually 4% higher, but 4%pts higher... which is different.
      All this to say, it was swaggy napkin math that is often approximate. Not a good excuse, but that's it.

    Thank you so much for taking the time to do this tutorial so clear, it has been most helpful. I just have one question on the forecasting section. When you first calculated the growth percentage, that percentage is with respect to Q1 2020, such that volume on Q1 2020 multiplied by (growth percentage + 1) returns the vol on Q1 2021. so, following this idea, the forecasted vol on Q2 2021 should be Q2 2020 multiplied by (growth percentage + 1), but the way you did it, as you explain on 27:30, is assuming that the growth percentage is with respect to 2021 and not 2020. I just want to know if this was a mistake or i'm missing something.

    • @mattbrattin
      @mattbrattin  Год назад

      Thanks for the question - yeah I did a bunch of stuff here and not all of it was explained very well. I think the part you're referring to I was attempting to say if we experienced X% YoY growth in Q1, then we could reasonable assume that same growth would continue into Q2. So, by applying this growth (from Q1) to Q2 of 2020 we get a projection of what Q2 could look like if we'd trended out Q1 growth. I go on to show the variances against that expectation and likely this is where it's not super clear why I did that, but basically we're wanting to see if the growth from Q1 persisted through Q2, which it did not - it changed. Which...is normal. Hopefully that helps, but if not please let me know!

But that's not on you, that's me, I'm a slow learner and that's why I said it will take me some repeat views to understand better. And I'm not taking it as a bad thing, its actually good. Nothing which is worth learning is easy. I'll come back again and again on this project series, I think there's a lot to learn for me here as aspiring data analyst.

    Matt, at 24:01, I could not see the remaining code as your video was blocking it. Can you please shed more light on that. The whole concept of GETPIVOTDATA is totally new to me

    • @mattbrattin
      @mattbrattin  Год назад

      Dang, all this time and I didn't catch that! Sorry about that, yeah it's similar to how syntax referencing a normal data table will call out the table name and columns in whatever naming conventions you've provided. Main difference is there's more dimensionality involved in a GETPIVOTDATA formula, meaning it's more flexible to reference specifics that would otherwise need to be calculated.
      The best way to play around with this is to have a pivot table and off to the side anywhere NOT in the pivot table, set an = and just start moving the selection around a pivot table and see how the syntax changes with your reference. That will tell you a lot about the different moving pieces and those you can change around to make for more sophisticated references.
      Hope that helps!

    Thank you so much Matt that was fantastic. I really got surprised by your analytics, as a professional analyst of course it is easy for you to find the ratios and some feature engineering inorder to get a deep insight. As a beginner how can I get skilled in working with numbers and this kinda ratios? I always end up doing Elevator Analysis. How can I change it?

    • @mattbrattin
      @mattbrattin  2 года назад +1

      Glad you enjoyed it! We all have to start somewhere and I think the simple fact that you're asking the question is a huge step in the right direction - many people never even get to the point they realize elevator analytics is a thing and that's what they're doing. I would say try not to focus on learning a bunch of ratios - think about data/values and the relationship they might have with other values. Maybe they are correlated? Maybe one drives the other? But if you turn them into a ratio you'll be taking a peek and can determine whether anything interesting is happening. It all starts with being curious and just playing with the numbers you have. Over time you'll get a sense for which relationships in the data are worth digging into. You're on the right track!
