## Data Analysis 2: Data Visualisation – Computerphile

Seeing is believing – Dr Mike Pound helps us understand how to turn our datapoints into Powerpoints. This is part 2 of the Data Analysis Learning Playlist: https://www.youtube.com/playlist?list=PLzH6n4zXuckpfMu_4Ff8E7Z1behQks5ba

This Learning Playlist was designed by Dr Mercedes Torres-Torres & Dr Michael Pound of the University of Nottingham Computer Science Department. Find out more about Computer Science at Nottingham here: https://bit.ly/2IqwtNg

The ‘Chicken’ dataset was adapted from this dataset:

For a novice to practice, would be great if you could make the Chicken.csv file available for download???

On the last two graphs between diet B and C, the chickens on diet B appeared to be the youngest unlike the last box plot graph which shows that chickens on diet C are the youngest.
Someone noticed the same thing or it 's just me?

@15:00.. from 3 to 4 eggs are not a 20% increase but a 33% increase.. (3×1.20 = 3.6 and 3×1.33..= 4)

Came here for the data talk, got me some shared Frasier love! Great video

Im really regretting not studying computer science in nottingham. All of those people are awesome especially Dr. Mike. To have a class with him would be nice for sure.

Biggest advantage for crook politicians is that people by default don't understand data. Once they understand, this world would definitely be a better place.

Dr. Mike given this data and assuming that perhaps this is the only data we had – if one were to make an operational change to their chicken business, would it not be logical to alter the diet of the older chickens in order to test the diet hypothesis? (because we can not make the older chickens any younger)

Very interesting! Thanks 🙂

Very nice analysis on the age, diet, eggs part. Thanks for the nice vid, though.

farmers hate him. see how he gets younger chickens with this amazing diet

the hard part of this work is not the analysis, but the preparation. 9:1 of the work. the R/tidyverse is a good tool

This is an amazing set of talks on data. But, perhaps the most amazing part is the old dot-matrix paper you found!!!! Do they still make that????

Those down votes came from the pie chart enthusiasts.

Please have look again at the "bar chart for frequencies". you shouldn't use it to deduce the density or distribution. it's not a histogram unless you have a class width of one. it's the standardized frequency that you plot in a histogram. nice video though.

I had to look up the typical lifespan of a chicken, which is something I've never had pause to consider before.

This dude can explain the important concepts of data visualization better in mere 15 minutes than the professors at my university in 4 hours. Makes me even more miserable going there instead of just staying at home watching youtube videos.

I didn’t think I could like Dr. Mike any more than I already do, but then he said one of his favorite TV shows was Frasier and I was proven wrong.

Would that be too much if i ask for the upload of the sample data sheet?

Are the R scripts and csv files that are used available for download anywhere?
