How to compare
Overall size of data

Time line chart
Take time as the horizontal axis 、 The data is the vertical axis
- You can understand what changes have taken place in the data from the past to the present , You can also predict future trends through past changes

Correlation analysis method
What is it? ?
- The relationship between various data
What's the usage? ?

The greater the absolute value , The more relevant
- 0~0.3 low correlation
- 0.3~0.6 Moderate Correlation
- 0.6~1 Highly correlated
Positive and negative reflect the direction of correlation between the two data
