This is useful to visualize correlation of small data sets. I leave this as a food for thought for you, the Aspiring Data Scientist, to do a more detailed Exploratory Data Analysis.Īnalyze the 12th Standard Percentages with Graduation Percentages. Here, well describe how to produce a matrix of scatter plots. A Data Scientist should have the inquisitiveness to explore and investigate. The above statements are just hypotheses. Likewise, the weak correlation may be because the data is a mix of MBA Specialization in Finance, Marketing, HR, and Business Analytics.The weak correlation between MBA Grades and Graduation Percentages maybe because the Graduation Degree is a mix of B.COM, B.E., B.M.S, etc.A student who has secured very good percentages in the 10th standard is very likely to get good percentages in the 12th standard also. There is a moderately strong correlation between the 10th and 12th Standard Percentages.This shows strong negative correlation, which. This example shows how to plot a confidence ellipse of a two-dimensional dataset, using its pearson correlation coefficient. Using it you can find the correlation between the plotted variables. Negative correlation (red dots): In the plot on the left, the y values tend to decrease as the x values increase. Each off diagonal subplot contains a scatterplot of a pair of variables with a least-squares reference line, the slope of which is equal to the displayed. row three, column one is the intersection between AveRooms and MedInc) shows the scatter. A student having very good grades in graduation does not necessarily mean the student will pass the MBA with flying colors. Scatter Plot allows you to compare and find the relationship between the two variables. Each box that is an intersection of a variable with another (e.g.
