Day 9: Dataquest challenge : Completed Data Cleaning Walkthrough: Analyzing and Visualizing the Data

Week 2 : Day 9

Today, completed third task “Completed Data Cleaning Walkthrough: Analyzing and Visualising the Data”. In this coding exercise, I learnt more about data cleaning , calculate correlations and visualise the correlation between two variables using scatter plot. Scatter plot is a best method to visualise the correlation between two variables. if two variables are moving in left direction then they are negatively correlate and if moving in right direction then they are positively correlated. We most used the value of “r” , called Pearson correlation coefficient. 1 shows strong positive correlation, -1 shows strong negative correlation while 0 shows no correlation.
