Today we-re going to talk about measures of central tendency - those are the numbers that tend to hang out in the middle of our data: the mean, the median, and mode. All of these numbers can be called -averages- and they-re the numbers we tend to see most often - whether it-s in politics when talking about polling or income equality to batting averages in baseball (and cricket) and Amazon reviews. Averages are everywhere so today we-re going to discuss how these measures differ, how their relationship with one another can tell us a lot about the underlying data, and how they are sometimes used to mislead

No such thing as an average favorite color? In the digital age, I wouldn't be too sure about that. You could theoretically find the mean R, mean G, and mean B value and composite those three components into a sort of -mean- favorite color. In a very simple example, Roy likes red (255, 0, 0, Bill likes blue (0, 0, 255, Greg likes green (0, 255, 0, Yolanda likes yellow (255, 255, 0, and Pete likes purple (255, 0, 255. This would make the -mean- a color of about (153, 102, 102, which I believe would be a dull reddish tone. Just a bit of fun!

This is a fantastic introduction. I'm not a mathematically minded person, but am about to embark on a project that will require statistical analysis and this has been the best introduction I've found. Thank you!

This made me understand the concept rather than what books do, tell you how to calculate the central tendency values with vague explanations which then leads to memorizing and not thinking.

This was cool. It's not hard to understand what the difference between these three are but no one's ever explained to me how the relationships between them can be useful

It silly how she went from cats because of the 2. 5 cats average to macrame knots. Guess averaging 2. 5 cats isn't a fun visual aide. But the cats were so cute!

4: 14 I don't get this! Shouldn't the median be 3?
Edit: Ohhh the hell? I thought she was talking about the number of cats. I wish this was phrased better.

Please try to read at a more constant pace and volume, without putting emphasis on certain words. It makes it hard to listen. English is not Italian; -)

Wait, why would the median remain on 20k? The shouldn't the median be 510k? Since the largest data point changed, the median should also change, right?

this is the third video, i watched to understand this topic. Thank god the others were short. and: does she sound like Bill Hammack The Science Guy?

Of course you can have 2 and 1/2 cats: Schrodinger proved it with the through superposition with his cat being both alive and dead.
