We have to find sea level rise in past 100 years. The point is data helps you to find facts.Īlright so after this fake data let’s deal with real data. The girl did not perform well could have some domestic issue, or ill. There are chances that the guy who performed well was being strictly monitored by parents and he was asked to work well or guided well. Imagine if a school head hire a statistician, he would present this graph and then will ask the head to call these two buddies for their exceptional results. Graphs help you to find the fact and then investigate the causes this result got produced. Data tells you story, it helps you to investigate unknowns. The guy performed pretty well while a single girl did pretty bad. There are two outliers, one in guys and other in girls. The graph is clearly telling that girls performed way better than guys but. When it runs it produces a graph like below:īoys are in green while girls in red. We have grades available in two different lists and we are going to call scatter twice to plot different data sets. import matplotlib.pyplot as plt import pandas as pd girls_grades = boys_grades = grades_range = plt.scatter(grades_range, girls_grades, color='r') plt.scatter(grades_range, boys_grades, color='g') plt.xlabel('Grades Range') plt.ylabel('Grades Scored') plt.show() We are going to make a scatter plot for that. They allow us to identify and determine if there is a relationship (correlation) between two variables and the strength of that relationship. Scatter plots are a commonly used data visualisation tool.

The goal is to find out who performed better and how to get rid of shortcomings. Neutron density scatter plot / crossplot created with matplotlib in python.

The code below demonstrates that: import numpy as np import matplotlib.pyplot as plt Create data N 60 g1 (0.6 + 0.6 np.random.rand (N), np.random.rand (N)) g2 (0.4+0.3 np.random.rand (N), 0. In this class both guys and girls appeared in the exam. Scatter plot created with Matplotlib Scatter plot with groups Data can be classified in several groups. Suppose the result was announced for a class. First come up with an arbitrary but interesting example. It also helps it identify Outliers, if any.Įnough talk and let’s code. Scatter Plots are usually used to represent the correlation between two or more variables.

In last post I talked about plotting histograms, in this post we are going to learn how to use scatter plots with data and why it could be useful.
