Understanding Time Series Analysis - Seasonality

Time-Series Analysis is a statistical method used to analyze and interpret data points collected or recorded over a period of time. It aims to identify patterns, trends, and relationships within the data to make predictions or forecasts for future time points.

Seasonality is one of the elements in Time-Series Analysis, which refers to the repetitive and predictable patterns that occur at regular intervals within a time series data. These patterns can be daily, weekly, monthly, or yearly and are often influenced by seasonal factors such as weather, holidays, or cultural events. Identifying and accounting for seasonality is crucial in time-series analysis as it can significantly impact the accuracy of forecasts and predictions.
