## â€‹Probability Distribution Quiz - Test Your Knowledge

Probability Distributions aren't some mythical creatures sprinkled with magic pixie dust. â€‹They may be a bit of a mystery to some, but once you dive a little deeper you realise that **they're not so tough** after all.

How can you get one just from flipping a coin? Where does it come from? And â€‹what can you do with it?

Well, the mathematics behind â€‹â€‹probability distributions may be difficult to understand, but how â€‹they come about is actually quite straight-forward.

Don't believe me?

Then stick around and I'll prove it to you - after I've tested your knowledge with a short, fun â€‹â€‹â€‹probability distribution quiz.

â€‹Get started here to test your knowledge:

### Introduction to Probability â€‹Distributions

â€‹For a while now I've been researching all the little nooks and crannies of the statistics world to create a big picture of what it looks like when you pull it all together.

And this is what the part about Probability â€‹Distrâ€‹ibutions looks like:

So, how did you do in â€‹our little â€‹probability distribution quiz?

â€‹â€‹Well, â€‹our probability distribution quiz is actually one of the lessons in The Hive from our **exclusive** video course Statistics - The Big Picture, which is Open Access to start with (you don't need to register).

If you want to â€‹learn more about Probability â€‹Distributions and how â€‹they fit into the Big Picture of statistics, you can start from the beginning here:

### â€‹The 5 Most Awesome Things You Need to Know About Probability â€‹Distributions

â€‹I'm not going to go into great depth â€‹right now, because that's what the video course is for, but hereâ€‹ are the 5 most awesome things you probably didn't know about probability â€‹distributionsâ€‹:

- 1â€‹There are 2 types of probability distribution;
**Discrete**and**Continuous** - 2â€‹Every discrete distribution â€‹is
**twinned**with a continuous distribution - 3â€‹Each distribution is described accurately by a
**mathematical equation** - 4You can use this equation to predict a
**mean**and**standard deviation** - 5These predictions can be compared with the actual mean and SD to determine whether
**the difference between your data and the theoretical distribution is significant**

### A Summary of â€‹Probability â€‹Distributions

Probability distributions might seem like a bit of a mystery, but really they aren't.

Just by flipping a few coinsâ€‹, it becomes simple to realise that **some outcomes are much rarer than others**. We all know that getting 10 Heads in a row is a rare event, but getting 5 Heads and 5 Tails (in no particular order) is just what we expect.

Plotting the outcomes gives us a way of identifying the common and the rarer results - the common results are always in the middle and the rarer results are always in the extremes.

Running lots of experiments wth lots of coins gives us a nice, neat graph that we call the Binomial Distribution, which is just one of many â€‹examples of probability distribution.

And these distributions are *â€‹useful*â€‹.

We can use â€‹them to **compare what we expect to find with what we actually find**, and use â€‹â€‹them to tell us how likely it is that our result is important to us.

â€‹â€‹â€‹Probability distributions might not be sexy, but I reckon they're as cool as the Jamaican bobsled team...
