Today I continued the intermediate Python course in Dataquest and I will probably do it along with the statistics course.
- This explains the difference between .iloc and .loc in pandas very clearly https://stackoverflow.com/questions/31593201/how-are-iloc-and-loc-different#:~:text=loc%20gets%20rows%20(or%20columns,not%20present%20in%20the%20index.
- Uncomment in Python: Ctrl + /
Also, I learned about frequency distributions in Python and differences between histograms and barplots (I refreshed my memory on these). Here are some of those differences:
- Histograms help us visualize continuous values using bins while bar plots help us visualize discrete values.
- The locations of the bars on the x-axis matter in a histogram, but they don’t in a simple bar plot.
- Lastly, bar plots also have gaps between the bars, to emphasize that the values are discrete.
Also an interesting plot for exploratory analysis is scatter matrix plot (scatter_matrix function).
Finally, I uploaded this https://github.com/AngelosTheodorakis/Data_Analysis_Projects/tree/master/Visualizing%20Earnings%20Based%20On%20College%20Majors on Github , as part of a project on Dataquest, where I worked on some plots in Python (histograms, barplots etc.).It is the first project I upload in a Jupyter notebook format.
