## Exploratory Data Analysis in Python

ðŸ‘‹ Welcome to your workspace! Here, you can write and run Python code and add text in Markdown. Below, we've imported the datasets from the course *Exploratory Data Analysis in Python* as DataFrames as well as the packages used in the course. This is your sandbox environment: analyze the course datasets further, take notes, or experiment with code!

```
# Importing course packages; you can add more too!
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
import scipy.stats
import scipy.interpolate
import statsmodels.formula.api as smf
# Importing course datasets as DataFrames
brfss = pd.read_hdf('datasets/brfss.hdf5', 'brfss') # Behavioral Risk Factor Surveillance System (BRFSS)
gss = pd.read_hdf('datasets/gss.hdf5', 'gss') # General Social Survey (GSS)
nsfg = pd.read_hdf('datasets/nsfg.hdf5', 'nsfg') # National Survey of Family Growth (NSFG)
brfss.head() # Display the first five rows
```

`# Begin writing your own code here!`

#### Don't know where to start?

Try completing these tasks:

- Begin by calculating the number of rows and columns and displaying the names of columns for each DataFrame. Change any column names for better readability.
- Experiment and compute a correlation matrix for variables in
`nsfg`

. - Compute the simple linear regression of
`WTKG3`

(weight) and`HTM4`

(height) in`brfss`

(or any other variables you are interested in!). Then, compute the line of best fit and plot it. If the fit doesn't look good, try a non-linear model.
