Probability Basics
What is Probability in Data Analytics
Probability in data analytics is the measure of how likely an event is to occur. It helps analysts make predictions based on data. Therefore, probability basics for data analytics are important for beginners.
Why Learn Probability Basics for Data Analytics
Probability basics for data analytics help in forecasting and decision-making. They are used in machine learning and statistics. In addition, they help handle uncertainty in data.
Key Concepts in Probability Basics
Experiment
An experiment is an action that produces outcomes, such as tossing a coin.
Outcome
An outcome is a possible result of an experiment.
Event
An event is a set of outcomes.
Sample Space
Sample space is the set of all possible outcomes.
Formula of Probability
Basic Formula
Probability = Number of favorable outcomes / Total number of outcomes
Example
Total outcomes = 2 (Head, Tail)
Probability of Head = 1/2
Types of Probability
Theoretical Probability
Based on possible outcomes.
Experimental Probability
Based on actual experiments or data.
