Python and R as tools of data analysis and building psychological experiments
In this post, we will learn how make scatter plots using R and the package ggplot2.
More specifically, we will learn how to make scatter plots, change the size of the dots, change the markers, the colors, and change the number of ticks.
Furthermore, we will learn how to plot a trend line, add text, plot a distribution on a scatter plot, among other things. In the final section of the scatter plot in R tutorial, we will learn how to save plots in high resolution.
Data visualization is a big part of the process of data analysis. In this post, we will learn how make a scatter plot using Python and the package Seaborn. In detail, we will learn how to use the Seaborn methods scatterplot, regplot, lmplot, and pairplot to create scatter plots in Python.
More specifically, we will learn how to make scatter plots, change the size of the dots, change the markers, the colors, and change the number of ticks. Furthermore, we will learn how to plot a regression line, add text, plot a distribution on a scatter plot, among other things. Finally, we will also learn how to save Seaborn plots in high resolution. That is, we learn how to make print-ready plots.
In this post, we will learn how to read and write JSON files using Python. In the first part, we are going to use the Python package json to create and read a JSON file as well as write a JSON file. After that, we are going to use Pandas json method to load JSON files into Pandas dataframe. Here, we will learn how to read from a JSON file locally and from an URL as well as how to read a nested JSON file using Pandas.
Finally, as a bonus, we will also learn how to manipulate data in Pandas dataframes, rename columns, and plot the data using Seaborn.
With ever increasing volume of data, it is impossible to tell stories without visualizations. Data visualization is an art of how to turn numbers into useful knowledge. Using Python we can learn how to create data visualizations and present data in Python using the Seaborn package.
In this post we are going to learn how to use the following 9 plots:
As previously mentioned in this Python Data Visualization tutorial we are mainly going to use Seaborn but also Pandas, and Numpy. However, to create the Raincloud Plot we are going to have to use the Python package ptitprince.
