This short tutorial shows how to find the R squared value in Python using sklearn which can be useful when looking at the data correlation in a scatter plot.

## R Squared in Python

First and foremost, make sure you have sklearn installed which can be installed with bioconda.

Now, there is below the Python code for the r squared calculation.

```
from sklearn.metrics import r2_score
# define x and y
x = [3, -0.5, 2, 7]
y = [2.5, 0.0, 2, 8]
# r square estimation
r_squared_value = r2_score(x, y)
>>> r_squared_value
>>> 0.9486081370449679
```
