During Jeff’s workshop, we played with a lot of data sets and were armed with Excel skills. For me, after constructing the Excel tutorial and did a review of Excel, the knowledge would be as solid as possible.
1st data set is from world bank: life expectancy at birth.
Just remember that every time you play with a data set, just make a copy it, and keep the original in case that you mess up with the data.
- Make a copy of your data within the same file, just a new worksheet and rename it;
- Clean the data for your specific use:
- Hide unnecessary columns, in case that they would be useful later; (Unhide by selecting the columns surrounding them)
- Format number (Click on the left top corner so that you could select all);
- Freeze panes to lock the column header;
- Format auto column width;
- Use shift key to select a row or column range;
- Use filter to filter the blanks;
- Filter is stupid to do multiple choices;
The story: China has the most increasing number of life expectancy from year 1996 to 2014 among 10 biggest countries.
2nd data set is from U.S. Census: Imports in the U.S.
3rd date set is from U.S. Patent and Trademark Office
