5. Confidence Interval

This section will help us deal with the first real statistical case: finding confidence intervals. It requires knowledge of NumPy, pandas, Matplotlib, and Seaborn library to calculate math formulas and build visualization! To encourage you to pass this section, I want to point out that you will run across a small amount of theory but a significant amount of practice!

6. Statistical Testing

An inseparable part of a data analyst's life is conducting hypothesis testing. After completing this section, you will understand the idea behind testing in statistics and will be able to conduct a t-test using Python.

Examine the Dataset

In this section, we will analyze a sample of IT specialists' salaries. Let's first take a look at the first five observations of the dataset:

	work_year	experience_level	job_title	salary	salary_currency	salary_in_usd	company_location	company_size
0	2020	MI	Data Scientist	70000	EUR	79833	DE	L
1	2020	SE	Machine Learning Scientist	260000	USD	260000	JP	S
2	2020	SE	Big Data Engineer	85000	GBP	109024	GB	M
3	2020	MI	Product Data Analyst	20000	USD	20000	HN	S
4	2020	SE	Machine Learning Engineer	150000	USD	150000	US	L

work_year - this year, the salary was paid;
experience_level - the experience level: EN is Entery-level, MI is Mid-level, SE-Senior-level, EX is Executive level;
job_title - the name of a job;
salary - the value of the salary;
salary_currency - the currency of the salary;
salary_in_usd - the value of the salary in USD;
company_location - the location of the company;
company_size - the size of the company: S-Small, M-Medium, L-Large.

Now, let's review the data types in statistics, and afterward, you'll match each column name with its respective type.

Everything was clear?
