In this chapter, we’ll begin our journey by understanding the different types of time series that exist, as well as the analytical methodologies to analyze this. Once you’ve understood the fundamental concepts, you’ll learn how to reformat time series data in preparation for univariate and multivariate visualizations.

Introduction to Time Series Analysis in Tableau

Everyone wants to analyze data, but it’s important the data is clean. In this chapter, we’ll learn how to clean up time series data using Tableau’s inbuilt date functions where we’ll reshape, split and rejoin our data based on the different time context we’re interested in. Beyond this, we’ll dive into the concepts of seasonality, trend analysis and anomaly detection!

Date string manipulation and reformation

Data Preparation for Time Series Analysis

In this final chapter, you’ll learn all about the powers of window functions and statistical techniques like Z-Values, where you’ll create your very own anomaly classifiers to identify optimal pricing arbitrage opportunities for a trading company! In the second part of this chapter, we’ll compare multiple anomaly detection techniques, equipping you with a broad range of approaches to treating and analyzing time series!

<h2>Discover the power of time series</h2>
You’ll start with the basics where you’ll learn the different types of time series that exist, as well as the analytical methodologies to analyze this. Once you’ve got the fundamentals down, you’ll learn how to reformat time series data in preparation for univariate and multivariate visualizations.

<h2>Data Preparation & Time series</h2>
Everyone wants to analyze data, but it’s important we clean this up as well. We’ll learn how to clean up time-series data using Tableau’s date functions where we’ll reshape our data based on the different time context we’re interested in. Additionally, we’ll learn the ins and outs of using LODs to automate these calculations for us!

Time Series Analysis in Tableau

Z-score measures the relative position of a data point as a number of standard deviations, the standard deviation quantifies the dataset's spread

Z-score measures the dispersion of data points from the mean, while the standard deviation represents the average distance from the median

Z-score calculates the average distance between data points, while the standard deviation determines the likelihood of extreme values occurring

Z-score represents the proportion of data points within a certain range, while the standard deviation determines the skewness of the dataset
