-
00:00:00No matter what type of analytics that you're doing or how much data that you're using analytics, typically falls into one of four major categories
-
00:00:09Today, we're going to look at those four types of analytics analytics, it's a really broad term
-
00:00:16It covers a wide variety of details levels and data volumes but no matter what type of analytics are performing and what you're trying to achieve, you can usually categorize at one of four ways, you are
-
00:00:32typically going to want to either describe, diagnose predict or prescribed, these four types of analytics and build off of each other
-
00:00:41These four stages of analytics describing diagnosing, predicting and prescribing will feel very familiar if you've ever been to the doctor because you weren't feeling
-
00:00:51Well, let's look at what that might look like you went to bed last night, feeling fine, but you woke up this morning feeling any But fine
-
00:01:01Maybe you're a little achy and you have some chills you suspect
-
00:01:05You might have a fever
-
00:01:06So you take your temperature and find that it's a few degrees higher than normal
-
00:01:10At this point, you've described what's happening and now, maybe you make the decision to go to the doctor to get checked out
-
00:01:19Once they're the doctor asked you questions which go over the described process
-
00:01:24Again, they might even recollect information, they'll probably take your temperature themselves to check it, and they might check your heart rate in your blood pressure at the same time
-
00:01:34Now, they move on to trying to figure out what this means, based on all your symptoms, the doctor diagnoses that you most likely have the flu, you might be given a rapid flu test but that
-
00:01:47often doesn't change what the treatment is at this point we reached the diagnostic stage
-
00:01:52Now what happens if you don't do anything, many people feel miserable for a few days but then work
-
00:02:00Just fine from the flu on their own, but maybe there is underlying health problems
-
00:02:05Are other risk factors that make it more likely that you won't recover is easily the doctor talks with you and text your medical records and finds
-
00:02:13There's nothing that makes you especially vulnerable
-
00:02:15So at this point, they predict that with rest and sometime you'll feel better on your own at this point
-
00:02:24A prediction has been made that you'll be fine without any additional medical treatment, the doctor, then send you home with instructions to rest, drink, plenty of fluids and to take an over-the-counter pain
-
00:02:36Reliever, if the eggs get to be bothersome at this point, you have a prescription
-
00:02:42You've been prescribed rest fluids and over-the-counter pain
-
00:02:48Reliever if necessary, this is how you optimize the Improvement
-
00:02:52Will you get better? Even if you don't do these things, most likely but this will help it go faster and for you to feel bad
-
00:03:00As you're getting healthy again with this, we've just gone through these four stages of analytics
-
00:03:07We can use this exact same process to work through a problem and stop along the way wherever we need to reach
-
00:03:14Sometimes, the only thing we're trying to accomplish is to describe what's happening other times, we need to predict what's going to happen or prescribe, what will happen in the future
-
00:03:23Using the analogy of visiting the doctor
-
00:03:25If you woke up today and felt fine, there's really no need to go on and diagnose, predict, and prescribe you feel fine, Everything feels normal
-
00:03:36So the added value of doing this additional stages is minimal and the actual work as minimal as well
-
00:03:42Because we would assume that if we feel okay, that everything's going to be continuing to occur, we're going to continue to feel like we have felt unless we have some other information from a data and
-
00:03:55information standpoint
-
00:03:56Here's what those four types of analytics look like The most basic level we can produce regular can reports that tell us what happened within the business
-
00:04:06At this point, we're really just answering what happened or maybe we've gone a step further and we produce ad hoc reports that go into more tabs on how many when, and where both of these are
-
00:04:18descriptive analytics
-
00:04:20They provide basic expository information what when how many, how much at the next level? We start to query and drill down into our information, further
-
00:04:32We not only want to understand what happens
-
00:04:35We want to know why that it happened
-
00:04:37You also might create, indicators, are flags to notify you when this thing that you're studying occurs again in the future, when you do that, you're asking where do we look both of these are diagnostic analytics
-
00:04:52Diagnostic analytics are really focused on why something happened and how we're going to know if it's happening again
-
00:04:59Both descriptive and agnostic analytics
-
00:05:02Focus on the past
-
00:05:04It's all about what happened before the current point in time
-
00:05:08Now, we start to look towards the future when we get into Predictive Analytics and then prescriptive analytics Predictive Analytics, help you understand what variables are a play, how they relate to each other, and any correlation
-
00:05:22that might be present
-
00:05:24They really start to help you understand what happens in the future assuming that we changed nothing from an analytic standpoint
-
00:05:32We focus on statistical modeling and then move on to predictive modeling assuming that nothing changes
-
00:05:38What does the future hold in some cases, we might want to change what the future holds in that case were moving into, prescriptive analytics, prescriptive analytics, often starts with random testing, but if we just try
-
00:05:52this and then it moves onto optimization
-
00:05:56What's the best course, forward? What actions show? Do we take in prescriptive analytics? We're trying to predict the future based on changes to what's happened in the past
-
00:06:06I mentioned that these four types of analytics build off of each other
-
00:06:11If you want to predict what's going to happen in the future, you have to start with the scribing and then diagnosing, if you jump straight to predicting your predictions, likely not going to be very accurate
-
00:06:24or not, more accurate than random chance would allow for this reason, make sure you take time
-
00:06:29If you're predicting to also understand in detail what happened and why it happened
-
00:06:35But the only way to really understand what's going to happen, going forward
-
00:06:39The same thing with prescriptive analytics
-
00:06:41People often want to jump straight there because they want to make changes or they assume they know what happened but if you don't take the time to understand what really happened and why it happened and
-
00:06:53predicting what happens if nothing changes, then your prescription is likely to not being Credibly effective, you're going to miss out on key factors that you should have accounted for because you didn't take time to study
-
00:07:07the past correctly
-
00:07:09Like, I mentioned, this doesn't always have to be a long process
-
00:07:12If you woke up feeling fine this morning then you could run through the entire process and to end in a matter of a few seconds
-
00:07:21You would describe that everything feels normal or like you're used to
-
00:07:24You would diagnose that everything's
-
00:07:27Okay
-
00:07:27I'll predict that, it will continue to be fine and prescribed that you keep doing what you've been doing, even when something's wrong with this process, can go quite quickly
-
00:07:37If you woke up this morning and you had a headache, you might describe that
-
00:07:42You have a pressure in your head, you would diagnose
-
00:07:45That is a headache
-
00:07:46You would predict that overall you don't feel too bad
-
00:07:50And so you're probably be fine throughout the day and then you'll prescribe that you either tolerate it without doing anything or you
-
00:07:57Take some specific actions that You know, if help to mitigate headaches in the past, all of that could probably happen in 5 to 10 seconds at most
-
00:08:06Usually, any analytics activity will be pretty clear from the start
-
00:08:11What's the age that you need to read? You'll know whether you just need to describe whether you need to diagnose and explain
-
00:08:18The why, or whether you need to predict, or prescribe what to do in the future that we've covered descriptive analytics by Gnostic analytics Predictive Analytics and prescriptive Analytics
