Risk

The uncertainty associated with any investment. That is, risk is the possibility that the actual return on an investment will be different from its expected return. A vitally important concept in finance is the idea that an investment that carries a higher risk has the potential of a higher return. For example, a zero-risk investment, such as a U.S. Treasury security, has a low rate of return, while a stock in a start-up has the potential to make an investor very wealthy, but also the potential to lose one's entire investment. Certain types of risk are easier to quantify than others. To the extent that risk is quantifiable, it is generally calculated as the standard deviation on an investment's average return.

This hypothesis is not substantiated by finding a correlation between the number of physicians and the number of deaths from X rays unless one accepts the conjecture, or guess, that the number of physicians can be used as a measure of X-ray exposure.
