Energy Usage in USA
We picked 10 states spread around USA and collected data on energy usage in each of their respective sectors and what and how energy each of the 10 states use.
1. Make a line graph of gasoline vs. transportation. What is the correlation efficient?
Correlation= -0.0931022
Correlation= -0.0931022
2. Make a histogram of coal. Is the data skewed to the right, left or symmetric?
Data is skewed to the right
Data is skewed to the right
3. Plot a line graph using coal vs. industrial. What is the correlation efficient?
Correlation efficient is 0.6473648.
