Randomize data with LINQ

- [Instructor] Randomized sampling of data…is important in many scenarios.…For example, in some cases,…it helps cancel the effects of confirmation bias.…It can smooth over unintended patterns…in the data collection.…It's an essential component in most scientific trials.…In this tip, I'll look at how to use the LINQ tools in .NET…to quickly run a randomized query against the data set.…Yes, there are other ways to implement this.…For example, with a specialized shuffle algorithm.…But this example is quick and easy.…

For this example, I'm using a WPF application.…That way, I can show you a simple bar graph…with a randomized data.…I've got three charts in this window.…The top one, the red one, is bound to the data source…and I've done nothing special to it.…It's showing the data…in the order that is coming from the data source.…The orange graph and the blue graph…are both bound to the same underlying data source…as the red graph, but this time,…I'm using the tip to randomize the appearance of the data.…
