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
The distribution is bimodal. That is all there is to it.
bimodal histogram is a histogram where there are two clear high points on the graph. ex.) age of people at a preschool play group. There would be preschool age and adult age. Not many teenagers or elderly. Bimodal...the ages representing preschool and adult (parents?) would stand above the rest
It is called bimodal.
The modes of a probability density function might be defined as the (countable) set of points in the domain of the function for which the function achieves local maxima. Since the probability density function for the uniform distribution is constant by definition it has no local maxima, hence no modes. Hence, it cannot be bimodal.

bimodal is having two modes and if you can recall the mode is the number that appears most often, so that means that a bimodal set of numbers has two modes. ex. 9,5,9,7,1,5,6 this set of numbers is bimodal with a mode of 5 and 9.
no
yes
By specifying the centre and standard deviation of the distribution but also mentioning the fact that it is bimodal and identifying the modes.
The distribution is bimodal. That is all there is to it.
This could be a bimodal. There are many other factors that would have to be taken into account as well.

Seminomas and Osteosarcomas are two examples
Yes then it would be considered bimodal.
It is called bimodal.
A bimodality is a bimodal condition - a distribution which has two modes.
