Free Databases and Data Visualisations course for kids Week 7

Yesterday I gave the results for the database fundamentals test that was conducted last Monday. If anyone wants to try the test you can click here
 #microsoftnz, #sqlserver,  #sqlfamily

I started off the class with an introduction to Data Visualisation.  Why we need data visualisations and type of data visualisations.  Also covered different tools for data visualisations. Finally I introduced what Power BI Desktop is. hashtag#powerbi, hashtag#powerbiusergroup.

Had an interactive session with a lot of questions from the kids like 'What is a Heat Map ?' 'What is the difference between pictorial and graphical presentation' etc.

Shared a movies csv file and introduced the Get Data button in Power BI Desktop and got all of them to download the movies database.  Explained how to create the main visuals -- the column chart and stacked bar charts.  What kind of columns can be used in the Values part of the visuals.
Gave them homework to create their own visuals and present them in the next class.
I have also asked them to download the country latitude and longitude dataset that is available here
https://lnkd.in/gN72ccD by using the Get Data -- web button with a view to teach them about Maps in the next class.

I am looking forward for their creations next week.
