You are likely familiar with the probability density function of the normal distribution--that is, the bell-shaped curve.
A bimodal distribution is one whose probability density function has two 'humps' or maxima. In other words, values of the random variable are more likely to occur around where those two maxima occur than elsewhere, in the same way that values of a normally distributed random variable are more likely to occur around its maximum.

Is normal distribution bimodal?
no
How can the measures of center and spread of a bimodal distribution be described?
By specifying the centre and standard deviation of the distribution but also mentioning the fact that it is bimodal and identifying the modes.
Does a normal probability distribution include a bimodal distribution?
No, the normal distribution is strictly unimodal.
Is A distribution is noticeably bimodal if the means of each distribution are separated by at least one standard deviation?
This could be a bimodal. There are many other factors that would have to be taken into account as well.
What Do You Call A Data Set With Two Modes?
A bimodal distribution.
Is normal distribution bimodal?

Does a normal probability distribution include a bimodal distribution?
No, the normal distribution is strictly unimodal.
What if there a two modal class?
The distribution is bimodal. That is all there is to it.
Is considerably skewed distribution the same as bimodal distribution?
No. A distribution may be non-skewed and bimodal or skewed and bimodal. Bimodal means that the distribution has two modes, or two local maxima on the curve. Visually, one can see two peaks on the distribution curve. Mixture problems (combination of two random variables with different modes) can produce bimodal curves. See: http://en.wikipedia.org/wiki/Bimodal_distribution A distribution is skewed when the mean and median are different values. A distribution is negatively skewed when the mean is less than the median and positively skewed if the mean is greater than the median. See: http://en.wikipedia.org/wiki/Skewness

What is a bimodality?
A bimodality is a bimodal condition - a distribution which has two modes.
What Do You Call A Data Set With Two Modes?
A bimodal distribution.
A type of selection where the normal distribution is pushed apart into two separate peaks?
Bimodal Distribution
What is name of 2 modes?
A distribution with 2 modes is said to be bimodal.
Why is there a bimodal distribution of elevations on the surface of the earth?
The bimodal distribution of elevations on Earth's surface is due to the presence of both ocean basins and continental landmasses. The ocean basins are generally lower in elevation, while the continental landmasses have higher elevations, resulting in the bimodal distribution commonly observed.
What do you do when you have two modes in maths?
Nothing. You simply have a distribution that is bimodal. You report both modes.
