statistics

A simple statistics project for small positive integers (bellow 1000):

the DataCapture class provide methods to add positive integers bellow 1000, to be queried with 3 comparisson methods (each of O(1)):

• less(n): returns the amount of numbers added, bellow the given n integer (not inclusive);
• between(n,m): returns the amount of numbers added, between the given n and m integers (inclusive);
• greater(n): returns the amount of numbers added, greater than the given n integer (not inclusive);

Installing dependencies:

To get pytest to run in your virtualenv, install the dependencies with either

pip3 install pytest

or

pip3 install -r requirements.txt

Usage:

Once cloned you can import the DataCapture class from DataCapture.py to instantiate data capturing objects, responsible for storing data with an add method. The object is also capable of returning a stats object, which contains methods to query the simple statistics information from the added data (less, between and greater):

from DataCapture import DataCapture


capture = DataCapture()

# adding data:
capture.add(3)
capture.add(9)
capture.add(3)
capture.add(4)
capture.add(6)

# generating the stats object:
stats = capture.build_stats()

# querying statistics information:
stats.less(4) # return 2 (only two values 3, 3 are less than 4)
stats.between(3, 6) # return 4 (3, 3, 4 and 6 are between 3 and 6)
stats.greater(4) # return 2 (6 and 9 are the only two values greater than 4)

Runing tests:

Run on terminal inside the project's root folder:

pytest -q TestDataCapture.py
