Here's an item sure to stir up generational tensions: The American Management Association says Millennials just don't have the analytical skills of older generations.

In fact, 19 percent of the younger generation has either non-existent or poor analytical abilities, according to a study sponsored by the association.

The organization asked nearly 800 respondents from more than 50 industries how prepared they are to compete in an age of big data. Generation X — those  between the age of 30 and 50 — was the most analytical of any group, with 58 percent rated as advanced or expert and only 6 percent rated non-existent or poor. Forty-one percent of baby boomers fell into the advanced or expert category, along with 35 percent of Millennials.
