The Complete Python Course - 4 Coding Examples - Statistics Module Functions

The video tutorial demonstrates how to set up a project in PyCharm and create a Python file. It covers using the statistics module to calculate mean, median, mode, and standard deviation of data. Each section provides examples and instructions on how to implement these statistical functions in Python, highlighting the use of aliases and the importance of importing the correct modules.

What is the first step in creating a new project in PyCharm?

• Select 'New Project' from the file menu

• Open the terminal

• Right-click on the desktop

• Press Ctrl + N

Which Python module is used to calculate the mean of a dataset?

• math

• numpy

• statistics

• pandas

What is the purpose of using an alias when importing a module in Python?

• To increase the execution speed of the code

• To shorten the module name for easier reference

• To automatically update the module

• To avoid importing unnecessary functions

Which function is used to calculate the median in the statistics module?

• mean()

• median()

• mode()

• stdev()

What is the primary function used to find the mode of a dataset in Python's statistics module?

• stdev()

• mean()

• median()

• mode()

Which function is used to calculate the standard deviation of a sample in Python?

• mean()

• median()

• mode()

• stdev()

What is the purpose of the stdev function in the statistics module?

• To compute the standard deviation of a sample

• To determine the mode of a dataset

• To find the median of a dataset

• To calculate the mean of a dataset
