While we briefly touched upon some forecasting in the class in terms of correlations (if you remember back in Week 4), I did want to provide two additional stories on forecasting and that is leveraging the wisdom of the crowds for forecasting.

Listen / read these stories by NPR and respond to the questions below:

• Kestenbaum, David. (Aug 20, 2015). Weighty issue: Cow guessing game helps to explain the stock market. NPR.Links to an external site.
• Spiegel, Alix. (Apr 2, 2014). So you think you\'re smarter than a CIA agent? NPR.Links to an external site.

Questions:

• Can you think of ways corporations might leverage this notion?
• Is there a way that companies like Amazon already use the \"wisdom of the crowd\" to try to predict your satisfaction in a product? How is this done? Is this a valid process? Why or why not?
