![]() This can be defined in LookML as a measure of type: median. Half of your data values are less than or equal to this value. Median: A measure representing the median or midpoint of the dataset, or the second quartile.This can be defined in LookML as a measure of type: percentile with the value for percentile set to 25. One quarter of your data values are less than or equal to this value. 25th percentile: A measure representing the 25th percentile, or the first quartile.This can be defined in LookML as a measure of type: min. Minimum: A measure representing the minimum data value.Traditional boxplot visualizations require at least one dimension, and the following five types of measures (which must be in this order, from left to right): Compared to other traffic sources like Email, which has a third quartile value of 10 lifetime purchases, users from the Display traffic source tend to make fewer lifetime purchases. It also has a third quartile value of 5 lifetime orders, showing that three quarters of users from the Display traffic source have fewer than 5 lifetime purchases. This example shows the values for the Lifetime Orders field based on the Traffic Source dimension:ĭisplay has a median value of 3 lifetime orders per user, with minimum and maximum values of 1 and 14 lifetime orders per user, respectively. Next, select the Edit option on the visualization bar to edit your chart. To use a boxplot visualization, select the ellipsis (.) in an Explore Visualization bar and choose Boxplot. Each row in the Data table for your query becomes one box in the chart. A horizontal line through the box represents the median value. The "whisker" portions of the chart, which are the lines that extend vertically from the top and bottom of the box and end at the maximum and minimum values in your data, represent the remaining 50% of values. The box portion of the chart represents the values between the first and third quartiles, where 50% of your data is contained. Your data values are organized from smallest to largest and then that list is divided into quarters. To create a traditional boxplot, your data should be separated into quartiles, or quarters. Boxplot charts can be especially useful for comparing values across categories. Boxplot charts help you visualize the distribution and spread of values in your dataset.
