Today we’ll walk through the process of creating a virtual environment and running a simple Python program. Virtual environments are essential because it helps to keep projects organized and isolated. Prerequisites Before we start, make sure you have the following: Installing the Virtual Environment 1) Check Your Python Version: Ensure your Python version is 3.3 …
Python Variable Naming and Assigning Value
A Variable is a placeholder that holds different data types as values. To assign a value to any variables, we use assigning operator (=) equal sign. So, the text on the left of the equal sign is the variable, and the right side holds the variable’s value. While creating any variables, please make sure to …
Population and Sample Standard Deviation
To measure the spread of a dataset we use standard deviation (sd). A higher standard deviation means numbers are more spread out in the data set while a low standard deviation indicates closer to the mean. Two types – The greek letter sigma σ indicates population standard deviation and “s” denotes sample standard deviation. Formula …
The measure of Central Tendency: Mean
Mean is the average of a data set. It is one of the most common methods to identify the central position. To calculate the Mean, Need to sum of all the values in the data set. Divide the sum by the number of values in the data set. Formula of Mean Here, The lower-case Greek …
Residual in Regression Analysis
Residual is the vertical distance between the observed actual value (dependent variable) and the predicted value (generated by regression equation). Formula to calculate Residual e = y – ŷ Here,e = Residualy = Observed Actual valueŷ = Predicted value 1) Observed Value (y) higher than the Predicted value (ŷ) – Positive Residual 2) Predicted value …
Text File Reading, Writing and Closing in Python
In python, there are several ways for reading, writing and closing a file. Such as by using Numpy or Pandas libraries. However, Python also has its own built-in function to read or handle a file. Throughout this article, we will learn about python file handling, for which we will use the open() and then with …
