Correlation LAB in python for data science.

Learn to calculate the correlation between variables and quantify the degree of association using correlation coefficient using the lab exercise. The video provides details on the lab exercise to explore correlation using a data set - AirTravel. Find out how the number of passengers and promotional budget is correlated, and the correlation between number of passengers and inter metro flight ratio.

Data scientist is called as the sexiest job of the 21st century.

Our "Machine Learning" course is now available on Udemy

Part 1 – Introduction to R Programming.
This is the part where you will learn basic of R programming and familiarize yourself with R environment. Be able to import, export, explore, clean and prepare the data for advanced modeling. Understand the underlying statistics of data and how to report/document the insights.

Part 2 – Machine Learning using R
Learn, upgrade and become expert on classic machine learning algorithms like Linear Regression, Logistic Regression, and Decision Trees.
Learn which algorithm to choose for the specific problem, build multiple models, learn how to choose the best model and be able to improve upon it. Move on to advance machine learning algorithms like SVM, Artificial Neural Networks, Reinforced Learning, Random Forests and Boosting and clustering algorithms like K-means.

Thanks. Very good explanation. Please share the AirPassenger.csv dataset used.

Where can I download the sample dataset used?

Hello madam, i have question, if correlation is negative then graph of scatter plot should show decreasing values points but in your example graph is same as positive correlation How its possible? Or Can you explain the difference between these two graphs? one for correlation value=0.98 approximately and second one is =-0.8 with the help of your graph output(because these two graphs shows same increasing trend)

help me out: i get

np.corrcoef(air.fiftyeight, air.sixty)
