we learn from data by analysing the data with sta-tistical methods. Therefore statistics will in practice involve mathematical mod-elling, i.e. using som. linear or non-linear function to model the particular phe-nomenon. Similarly, the use of probability theory as the concept to describe ran-domness is extremely important and a.
Here we focus the basic analysis, concerned with evaluating data quality and and missing values. For descriptive statistics, see Section Descriptive Statistics. We assume you have loaded pandas and numpy as. Next, we do some examples of exploratory data analysis with pandas.

Reading data using pandas 15 #Read csv file df = pd.read_csv("http://rcs.bu.edu/examples/python/data_analysis/Salaries.csv") There is a number of pandas commands to read other data formats: pd.read_excel('myfile.xlsx',sheet_name='Sheet1', index_col=None, na_values=['NA']) pd.read_stata('myfile.dta') pd.read_sas('myfile.sas7bdat')
In this step-by-step tutorial, you'll learn the fundamentals of descriptive statistics and how to calculate them in Python. You'll find out how to describe, summarize, and represent your data visually using NumPy, SciPy, pandas, Matplotlib, and the built-in Python statistics library.
