Tutorial: Designing a GraphQL API

This tutorial was created by Shopify for internal purposes. We've created a public version of it since we think it's useful to anyone creating a GraphQL API.

It's based on lessons learned from creating and evolving production schemas at Shopify over almost 3 years. The tutorial has evolved and will continue to change in the future so nothing is set in stone.

Mean -> Sum of all elements divided by number of elements. Arithmetic mean = average.
Median -> middle element after sorting all elements. If there are even number of elements, then get the mean of middle elements.
Mod -> Most repeated element (if there is one).
Range -> biggest element minus smallest element.


Standard deviation (sigma) -> how spread out the numbers are. Square root of variance.
Mean diviation - How far, on average, all values are from the middle. square root of absolute variance.
Variance (mu) -> average of squared differences from mean. That is (element - mean) squared for each element and find the mean of it.
