7 Data Exploration

8 Data exploration Data source :

9 Data exploration outliers

10 Data exploration Margin plots enable comparisons add context visualize the same fields in different ways

11 Data exploration Margin plots enable comparisons add context visualize the same fields in different ways

12 Data exploration using calculated fields

13 Statistical Modelling

14 Forecasting When to use : You have a time series You want to infer about future time series values

15 Forecasting Under the hood: Method - Exponential Smoothing Observations in the recent past are more predictive of the future than observations in the distant past.

16 Forecasting Under the hood: 95% prediction interval Tableau automatically selects the best of up to eight models, the best being the one that generates the highest quality forecast.

17 Trend Line When to use : To infer a relationship between two quantitative variables Used to show the overall pattern of a scatterplot Data Source:

18 Trend Line Line of best fit Under the hood: Method - Ordinary Least Squares What is the probability that this relationship is random? How much of the variations in divorce rate can be explained by salary?

19 Clustering Which customers should we target for the next Pinot campaign? What are the characteristics of the customers based on what they bought? Data source:

20 Clustering

21 Clustering When to use : To group particular set of objects based on their characteristics, aggregating them according to their similarities. Under the hood: Method k-means K-means locates centers through an iterative procedure that minimizes distances between individual points in a cluster and the cluster center

22 Clustering Cluster 1: Pinot Lovers! Cluster 3: Mostly sparkling drinkers Cluster 4: Small buyers
