A negative result means the test did not detect elevated levels of altered DNA and/or hemoglobin that could be caused by cancer or precancer in the colon or rectum. The test can also have a negative result that is incorrect (false negative). This means the test result missed a potential cancer or precancer.For that reason, it is recommended that you schedule regular screenings.Your doctor may recommend an alternative screening method.

The new distribution of the normal random variable Z with mean `0` and variance `1` (or standard deviation `1`) is called a standard normal distribution. Standardizing the distribution like this makes it much easier to calculate probabilities.
a distribution which is normal when the log values of the variable are considered. normal distribution. a graph of the distribution appears as a bell-shaped curve which is symmetrical on the two sides of the vertical axis through the peak of the curve. Called also gaussian distribution.parent distribution. the distribution (population) that was originally sampled. distribution which is normal when the log values of the variable are considered. normal distribution. a graph of the distribution appears as a bell-shaped curve which is symmetrical on the two sides of the vertical axis through the peak of the curve. Called also gaussian distribution.
